Android lint was erroneously warning that the forEach construct in
Kotlin required API 24+, which is incorrect, see
https://issuetracker.google.com/issues/185418482.
Work around that by forcing the Android lint version to 8.1.0.
This triggered some additional checks, which have been ignored, and a
new baseline.
This makes the notification view for a follow request contain more info about the new follower, and makes the layout (of their name / username) consistent with other notifications that show names/usernames.
* Disable lint checks for unused resource IDs
The check doesn't catch some instances where resources are used through viewbinding, and has too many false positives to be useful.
* Regenerate lint baseline
Delete the existing file, then regenerated with `.\gradlew lintBlueDebug -Dlint.baselines.continue=true`
* Enforce lint cleanliness when building
The volume of lintable issues is growing. To stem the tide:
1. Add `app/lint-baseline.xml`, which contains the current set of lint issues.
Any issue appearing here will not cause the build to fail.
2. Move lint configuration settings in to `lint.xml`.
3. Update the lint configuration so that any issue (i.e., any issue not
in lint-baseline.xml) causes a build failure.
4. Add the lint tasks as depedency when assembling an APK, to ensure the
lint checks are run.
* lint: Convert launcher images to webp
* Move lint.xml location
* Don't lint when assembling
* Update baseline
