eng: bump Microsoft.Bcl.AsyncInterfaces 10.0.6 → 10.0.7 to fix NU1605

System.Threading.Channels (resolved as 10.0.7 via Version="*")
transitively requires Microsoft.Bcl.AsyncInterfaces >= 10.0.7, but
the project pinned it at 10.0.6. This produced 5 NU1605 package-
downgrade warnings on every restore/build.

Bumping the direct reference to 10.0.7 aligns both packages to the
same .NET 10.0.7 release, eliminating all 5 NU1605 warnings.
Total build warnings: 12 → 7.
