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

libjxl: update to 0.10.2.
https://github.com/void-linux/void-packages/pull/49231

Description:
#### Testing the changes
- I tested the changes in this PR: **YES**
  - built only: `swayimg`, `kimageformats`
  - built and tested: `darktable`, `imlib2`, `krita`, `libjxl-*`

#### Local build testing
- I built this PR locally for my native architecture, (`x86_64-glibc`)
- built `libjxl` for `x86_64-musl` and `i686-glibc`, didn't build any of the other packages

I also went from using a `build_wrksrc` to a `skip_extraction` -> `vsrcextract` in the `libjxl` package since [I was told to do that before](https://github.com/void-linux/void-packages/pull/48828#issuecomment-1974843065) so it's probably the correct way of doing this kinda thing now
