Removed workaround for debugging source generators

[bkoelman]

Removed workaround for dotnet/roslyn#55802. The bug has been fixed in VS 2022 v17.2.

Note this PR solely affects debugging the source generator logic in the JsonApiDotNetCore codebase. This PR is unrelated to consumers of JsonApiDotNetCore that are debugging their source-generated controllers.
