There's a merged pull request on the void-packages repository

godot: update to 4.2.1.
https://github.com/void-linux/void-packages/pull/47576

Description:
#### Testing the changes
- I tested the changes in this PR: **YES** (As far as I could think of)

#### Local build testing
- I built this PR locally for my native architecture, (x86_64-glibc)
- I built this PR locally for these architectures (if supported. mark crossbuilds):
  - x86_64-musl
  - i686

Since we provide icu and brotli now in correct versions I've setup godot to use our packages instead of builtin variants.
