Change wording of triggers (#12715)

Browse Source 
* change wording

I think "trigger this automation" makes more sense than "fire this trigger".

* make terms consistent

Triggers are what starts the processing of an automation rule. It is possible to specify [multiple triggers](/docs/automation/trigger/#multiple-triggers) for the same rule - when _any_ of the triggers becomes true then the automation will start. Once a trigger starts, Home Assistant will validate the conditions, if any, and call the action.
### What are triggers
Triggers are what starts the processing of an automation rule. When _any_ of the automation's triggers becomes true (trigger _fires_), Home Assistant will validate the [conditions](/docs/automation/condition/), if any, and call the [action](/docs/automation/action/).
### Event trigger
Triggers when an event is being processed. Events are the raw building blocks of Home Assistant. You can match events on just the event name or also require specific event data to be present.
Fires when an event is being received. Events are the raw building blocks of Home Assistant. You can match events on just the event name or also require specific event data to be present.
Events can be fired by integrations or via the API. There is no limitation to the types. A list of built-in events can be found [here](/docs/configuration/events/).

Triggers when numeric value of an entity's state crosses a given threshold. On state change of a specified entity, attempts to parse the state as a number and triggers once if value is changing from above to below or from below to above the given threshold.

#### Sun elevation trigger
Sometimes you may want more granular control over an automation than simply sunset or sunrise and specify an exact elevation of the sun. This can be used to layer automations to occur as the sun lowers on the horizon or even after it is below the horizon. This is also useful when the "sunset" event is not dark enough outside and you would like the automation to run later at a precise solar angle instead of the time offset such as turning on exterior lighting. For most things intended to trigger during dusk or dawn, a number between 0° and -6° is suitable; -4° is used in this example:

### Template trigger
Template triggers work by evaluating a [template](/docs/configuration/templating/) on every state change for all of the recognized entities. The trigger will fire if the state change caused the template to render 'true'. This is achieved by having the template result in a true boolean expression (`{% raw %}{{ is_state('device_tracker.paulus', 'home') }}{% endraw %}`) or by having the template render 'true' (example below). Being a boolean expression the template must evaluate to false (or anything other than true) before it will fire again.

Webhook triggers are triggered by web requests made to the webhook endpoint: `/api/webhook/<webhook_id>`. This endpoint does not require authentication besides knowing the webhook id. You can either send encoded form or JSON data, available in the template as either `trigger.json` or `trigger.data`. URL query parameters are available in the template as `trigger.query`.

### Zone trigger
Zone triggers can trigger when an entity is entering or leaving the zone. For zone automation to work, you need to have setup a device tracker platform that supports reporting GPS coordinates. This includes [GPS Logger](/integrations/gpslogger/), the [OwnTracks platform](/integrations/owntracks/) and the [iCloud platform](/integrations/icloud/).

Geolocation triggers can trigger when an entity is appearing in or disappearing from a zone. Entities that are created by a [Geolocation](/integrations/geo_location/) platform support reporting GPS coordinates.
Because entities are generated and removed by these platforms automatically, the entity id normally cannot be predicted. Instead, this trigger requires the definition of a `source` which is directly linked to one of the Geolocation platforms.
