Update APKBUILDS to use Maintainer and Co-Maintainer instead of CODEOWNERS (MR 6272)

We now have a bot that reads those lines from APKBUILD files, instead
of using a proprietary gitlab feature. Relevant changes:

* Change @ollieparanoid for @Newbyte as maintainer for GNOME packages
  where Oliver was listed.
* Don't add @craftyguy as Librem5 maintainer, as he dropped it long
  ago
* Remove entries referencing archived ports
* Don't touch jenneron's maintainership. That's a task for another day
* Don't add "balejk" as maintainer. We have tried pinging them, but
  seem to be currently idle
  person is. Help figuring it out would be welcomed.
* Don't add "binarycraft" as maintainer. Last contribution was years
  ago: https://gitlab.com/binarycraft
* Don't add more maintainers to linux-postmarketos-qcom-msm8953, as it
  would have ended up with 7, which might be a bit too much
* Don't add more maintainers to the PinePhone. The current ones seem
  to actually be the most active
* Don't add Danct12 to N900. Sicelo has been single-handedly managing
  it for a long while
* Update maintainer emails for Nikita Travkin, Alexey Minnekhanov, and
  Barnabás Czémán

[ci:skip-vercheck] Co-Maintainer changes require no pkgrel updates
since the names do not make it to the package itself
