Fix NuGet packaging to handle dynamic glibc versions (#8474)

Browse source 
* Initial plan

* Fix NuGet package to support any glibc version

Make mk_nuget_task.py more robust by using pattern matching for glibc versions
instead of hardcoding specific versions. This fixes the issue where builds with
newer glibc versions (e.g., 2.39) were not recognized, causing the linux-x64
runtime to be missing from the NuGet package.

* Optimize regex patterns with non-capturing groups

Use non-capturing groups (?:) instead of capturing groups () for better
performance, as the captured groups are not used.
