We should branch .NET 10 shortly which means that main becomes and 11 branch. This issue will try to summarize what we need to do.

Current State
Waiting for branching

• Update download table to include RC1 and RC2 as well as any changes for main being 11(Update build table to rc1 dotnet#1941)
• Update branding so that 10.0.1xx branch is RC2 and main is 11.0.1xx-alpha
• Create a 10.0.2xx branch for live work
• Add interbranch flow between 10.0.1xx and 10.0.2xx
• Move localization to 10.0.2xx (wait until RC2 snaps for this)
• Update to a new target framework . These items should be done in this order roughly.
  • Add net11 framework references(Add net11.0 known framework references #50329)
  • flow net11 runtimes
  • update global.json to a new build that supports targeting net11
  • Retarget the sdk itself to net11
  • retarget the default templates to target net11
  • Revert dotnet/dotnet@a7ddbfe, the net10 KnownFrameworkReference has different RuntimePackRuntimeIdentifiers than net11
  • Unwind any changes needed from the transition (usually we have to pin templates and target the E2E tests at net10 until we have all of the upstream template updates)
