CI: Label include/*.h and include/nuttx/*.h as "Area: OS Components"

This patch fixes the PR Labeler, such that PRs with modified files in `include/*.h` and `include/nuttx/*.h` are labeled as "Area: OS Components". Previously the PR Labeler ignores files like `include/nuttx/elf.h`, which causes Build Jobs to be skipped incorrectly.
