[release/8.0-staging] [QUIC] Update MsQuic library version

[ManickaP]

Backport of #113159 from main (10.0) to release/8.0-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 - see commit 1207c32.

Regression

No

Testing

CI run - System.Net.Quic tests ran and passed, see #113206 (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.

LGTM, we need to update our dependencies to latest secure version.

The log shows 353 passing tests and names 2.4.8 as used MsQuic version.
