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.
This PR changes the Labeling of PRs so that the Architecture (arm, risc-v, xtensa, ...) is specified in the Board Label. Previously the CI Workflow would set Generic Board Labels like "Area: Board support". Now it will set the Arch-Specific Board Label like "Board: arm".
The Board Label will be used by the upcoming CI Build Rules to skip unnecessary builds. So "Board: arm" will enable only the builds for `arm-01` to `arm-14`. This is explained here: https://github.com/apache/nuttx/issues/13775
