Speed up unit tests

Contributor checklist

• This pull request is on a separate branch and not the main branch
• I have tested my code with the ./gradlew lintKotlin detekt test command as directed in the testing section of the contributing guide

Description

1. Matrix Strategy: I added a matrix strategy to parallelize the tests for the Conjugate and Keyboards flavors. This allows both sets of tests to run at the same time on different runners.
2. Pre-building APKs: I added a Pre-build Android Test APKs step that runs before the emulator starts. This prevents the build process from competing for resources with the emulator, which can lead to timeouts and slower test execution.
3. Removed redundant delays: I removed the sleep 30 and sleep 10 commands, as android-emulator-runner handles waiting for the device. I also removed redundant animation settings that are already handled by the disable-animations: true flag.
4. Workflow Cleanup:

• Renamed the "Run Ktlint" step in the test job to "Run Unit Tests" to accurately reflect that it runs ./gradlew test.

• Adjusted timeout-minutes to a more appropriate 45 minutes per parallel job.

• Investigate and speed up Android instrumentation tests #580

Maintainer Checklist

The following is a checklist for maintainers to make sure this process goes as well as possible. Feel free to address the points below yourself in further commits if you realize that actions are needed :)

• Tests for changes have been written and the unit test, linting and formatting workflows within the PR checks do not indicate new errors in the files changed

  • Tests may need to be reran as they're at times not deterministic

• The CHANGELOG has been updated with a description of the changes for the upcoming release and the corresponding issue (if necessary)
