Remove Alpine's maintainers and contributors from the APKBUILDs in temp
where we still had them. In general, we don't keep them there, because
we don't want them to get e-mailed about questions from the postmarketOS
aports. It is obvious that they were copy pasted from Alpine, with minor
adjustments.
Remove "Remember to increase pkgrel after changing _pkgver!" from
temp/mesa, because we have a CI check for that now.
[ci:skip-build]: cosmetic changes only
Rebuild to fix missing dependencies:
so:libicui18n.so.63, so:libicuuc.so.63
Currently we are facing another upstream compatibility issue with
Alpine, which is why CI will fail: polkit and therefore
networkmanager don't exist for armhf, armv7. See #244 for details.
Plasma-framework 5.55.0 isn't building for aarch64 without this patch.
Aleix Pol ran into the same problem with flatpak builds, and created the
patch: https://codereview.qt-project.org/#/c/253276/
Alpine Linux has updated their main/icu to 63.1, which means we have to
rebuild some of our packages too.
[skip ci]: simple pkgrel bumps, building won't finish in CI
