Now `develop` is aligned with `prerelease` and other branches, it contains the configuration for build release versions of the app.
Also many BuildConfig fields have been removed: some of them have been replaced by `BuildConfig.DEBUG`, instead of make that differentiation on branches; other didn't have sense to exist, so a comment has been left there.
Sentry logs ( before not present on `develop` ) have been added with a check `if (!BuildConfig.DEBUG)` for bein' executed only on release version.
Gradle version has been updated to 6.3 for being able to work with JDK 14.
Affected: Gradle version, release config for `develop`, Sentry logs on `develop`, BuildConfig fields
Ticket: none
