Update the "I'm Locked Out" documentation for using a container CLI (#18109)

* Update the "I'm Locked Out" documentation for using a container CLI

## Proposed change
Added steps to change a lost password through the command line when Home Assistant is running in a container. Also added a note that the "Change Password" button does not always show up, but switching to another interface will likely show it (I learned that _after_ figuring out this whole `hass` process).

## Checklist
* [x]  This PR uses the correct branch, based on one of the following:
  
  * [x] I made a change to the existing documentation and used the `current` branch.
  * [ ] I made a change that is related to an upcoming version of Home Assistant and used the `next` branch.
* [x]  The documentation follows the Home Assistant documentation [standards](https://developers.home-assistant.io/docs/documenting/standards).

* Update instructions for a forgotten password

- Moved the container command line instructions under the console instructions.
- Used wording from the section introduction to rename the authentication reset instructions.
- Removed mention of using a password manager since the user obviously did not (and HA has not been compatible with some password managers in some browser configurations recently). This is why I did not use one and why I had to figure out how to reset my password, then share the instructions with the community.
