  [GitHub] Fix `mlir:core` label definition (#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 very common directory
suffixes 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
