Update SBRP dependency

[mthalman]

The SBRP dependency is out of date by 5 months. This updates it in order to have access to System.Text.Json.7.0.3. This fixes the issue of that showing up as a source-build prebuilt.

Contributes to #69847

Shouldn't roslyn have a subscription from source-build-reference-packages?

Shouldn't roslyn have a subscription from source-build-reference-packages?

Seems like it should. I'm having darc issues preventing me from adding a subscription for some reason. Can someone else do it? I'm thinking it should mirror the config of source-build-externals:

https://github.com/dotnet/source-build-externals (.NET 8) ==> 'https://github.com/dotnet/roslyn' ('main')

@dotnet/roslyn-infrastructure - This is hitting a seemingly known test failure that I believe is unrelated to these changes. PTAL and merge if good. This helps to unblock dependency flow: dotnet/installer#17319
