Fix api generator and sdk-core protos path

[jmaeagle99]

What was changed

• Suppress performance analysis rule in API generator program.
• Fix protos path within sdk-core submodule.
• Regenerate protos based on current sdk-core submodule version.

Why?

I saw that the "Regen confirm unchanged" step of the CI workflow was failing silently. Example at https://github.com/temporalio/sdk-dotnet/actions/runs/20114313589/job/57719795349#step:7:21

• The update to .NET 10 likely caused the code analysis warning that fails the compilation of the Temporalio.Api.Generator project.
• After fixing the project compilation, the update to the latest sdk-core caused the project to not find the protos for regeneration since the crates were refactored.

Checklist

• How was this tested: Will check CI workflow
