[ci]: Made various changes for the electron app:

- Support for multiple electron targe per platform.
 - Removed packager CLI. Changed the logic we calculate the app name.
 - Fixed various OS-specific tests: stubbed `os`.
 - Restructured the final ZIP formats for Windows and Linux.
 - Added packager tests.
 - Switched from `@grpc/grpc-js` to native `grpc`.
 - Updated the version from 0.0.5 to 0.0.6.
