[release/9.0-staging] [QUIC] Update MsQuic library version

[github-actions]

Backport of #113159 to release/9.0-staging

Contributes to #113136

Customer Impact

Security in-depth change in msquic library - found internally.

We are updating just msquic dependency to 2.4.8 (we have reship msquic binaries on Windows -- on Linux we rely on external package published by msquic team directly). No unique changes to .NET code.

Note: We have done similar update in 2024/3 in 8.0 branch (9.0 hasn't had such change yet) - see commit 1207c32.

Regression

No

Testing

CI run - System.Net.Quic tests ran and passed - see #113205 (comment).

Risk

Low. Update of msquic library that is backward compatible (msquic team guaratnees it).
Also, customers on Linux get this version automatically with updates from their package managers.
