[llvm] [GitHub] Fix `mlir:core` label definition (PR #66556)

[Markus Böck via llvm-commits]

https://github.com/zero9178 created https://github.com/llvm/llvm-project/pull/66556

The current regex for the `mlir:core` PR label is too accepting. It uses `**` as a prefix for all paths, which allows any kind of directory prefix to be inserted when matching. Combined with directory suffices such as `IR` and `Transforms`, it leads to many false positives of being applied to PRs that do not touch MLIR core such as https://github.com/llvm/llvm-project/pull/66520

This PR therefore changes the `mlir:core` labels to only include the specified top-level directories if directly nested under either `lib` for source files, or `include` for header files
