fix: Update to Unity 2022.3.55f1

[bitsandfoxes]

The current LTS of Unity requires a bump to ndk: "r23b".
This PR contains workarounds for an ongoing issue with the current 2022 LTS. This requires us to fix an additional absolut path set in the gradle properties and to pin the targeted Android API target.

Additionally, for mobile project compilation, we're running on the big runners to stop the gradle build process to run out of memory.

I worry about how many different versions and checks are spread throughout the repo to get this to work. Is there a world we can keep a map of versions in a single file for example, that we parse and then things run on the correct version?

assigned @vaind for review here since he touched a lot of this stuff too

Looks reasonable to me

I get that and parts of it make me nervous too. But we've got the individual changes and checks bundled in their respective place, i.e.

• modify-gradle-project.ps1 contains all the changes to the exported gradle project to make it build in CI.
• Builder.cs contains all the changes necessary to properly create an artifact in CI.
