In Alpine-3.21.0-x86_64, when running runtime-libs.tests, System.Globalization.Tests and some other test categories will hit many failures related to the locale language environment.

The latest Alpine-v3.21-stable has been released on 2024.12.05: https://dl-cdn.alpinelinux.org/alpine/v3.21/
dotnet/runtime version: main branch or tag-v9.0.0

When I run the libs.tests in Alpine-3.21.0-x86_64, I found there are many failures related to the locale language environment, for example the following is the result of runtime-v9.0.0-libs.tests (the main branch can also hit these failures on Alpine-3.21.0):

• Alpine-3.21.0-x86_64 runtime-v9.0.0-Release-libs.tests:
  Total: 637937 ; Passed: 635956 ; Errors: 0 ; Failed: 442 ; Skipped: 1539 ; Time: 2001.94s;
  System.Globalization.Tests Total: 2666, Errors: 0, Failed: 190, Skipped: 16, Time: 6.845s

As said in https://github.com/dotnet/runtime/blob/main/docs/workflow/using-docker.md
Curently the lastest azure pipeline is Alpine-3.13-x64, and there are no failures related to the locale language environment:

• Alpine-3.13.0-x86_64 runtime-v9.0.0-Release-libs.tests:
  Total: 638216; Passed: 636426; Errors: 0 ; Failed: 51; Skipped: 1739; Time: 1965.82 s;
  System.Globalization.Tests Total: 2666, Errors: 0, Failed: 0, Skipped: 16, Time: 11.449s

I guess that the upgrade of the Alpine3.13.0->Alpine3.21.0 led to changes of the locale-related language environment, which triggered these failures.

May I ask if anyone can help to check if this is a problem? Does dotnet/runtime have plans to upgrade runtime tests to the latest version of Alpine-3.21 ?
Thank you very much!
