Description of the bug

Jellyfin 10.11.x fails to compile on Enterprise Linux systems older than EL9 due to a SkiaSharp platform issue.

Reproduction steps

Attempt to build Jellyfin 10.11.x with dotNet 9 on an EL8 (Rocky, Alma, CentOS Stream, Oracle, etc). Do the whole build and test process. During the test, the system will throw numerous errors about SkiaSharp (Or one of its components) not being able to load.

The exact same steps work fine on EL9 (Any variant).

What is the current bug behavior?

Jellyfin 10.11.x brings in SkiaSharp 3.116.1. Jellyfin 10.10.x used SkiaSharp 2.88.

After dissecting the problem for a while, one discovered that SkiaSharp 3.x has a bug in that the binaries provided link against GLIBC 2.29, which is only available in EL 9. EL 8 uses GLIBC 2.28.

This is not mentioned anywhere on the SkiaSharp website, but was discovered in the Github issues list. Here's the issue: https://github.com/mono/SkiaSharp/issues/3201 And they list it as fixed in 3.119-alpha, which has been replaced with a stable release since then.

What is the expected correct behavior?

The system should build on EL9 the same as EL8, since they both have dotNet 9 available. I am aware this is not a Jellyfin problem per se, but since SkiaSharp is required by Jellyfin, could we get it upgraded to SkiaSharp to v3.119.1? Assuming the version upgrade doesn't break something else.
