Managed symbols tarball seems to be missing files

[tmds]

We have a test that checks for managed symbols by expecting to find pdb files for the dlls in the shared framework.

I've enabled that test on our CI build to run with the managed symbol tarball that was added in dotnet/installer#17454.

The test is flagging missing pdbs.

Various builds report System.Threading.ThreadPool.pdb to be missing.

And one build (on Fedora 38 arm64) reports System.Text.Encoding.Extensions.pdb to be missing.
The System.Threading.ThreadPool.pdb may be missing here too, but the test bails as soon as it finds a encounters a missing pdb. Other builds report to have found System.Text.Encoding.Extensions.pdb.

I couldn't figure out the best area label to add to this issue. If you have write-permissions please help me learn by adding exactly one area label.

Closing as fixed by dotnet/installer#17533.

Thank you, @NikolaMilosavljevic!
