Add PR labeler with auto-generated content warning

[SusanneWindfeldPedersen]

What this adds

A GitHub Actions workflow (.github/workflows/pr-labeler.yml) that runs on every PR and:

1. Labels PRs by path — applies labels like
   eference-docs, \�pi, \developer, \�dministration, etc. based on which folders are touched.
2. Detects code changes — applies \contains-code\ when AL/JSON/XML code blocks are modified.
3. Detects auto-generated edits — applies \�dits-auto-generated\ when changes fall inside \DO_NOT_EDIT\ markers.
4. Identifies typo fixes — applies \ ypo-fix\ for small, non-structural changes.
5. Posts a warning comment (de-duplicated) when a contributor edits auto-generated content, explaining where to make the fix instead.

Why

External contributors sometimes edit content inside \DO_NOT_EDIT\ markers without realizing those sections are regenerated from source. This gives them immediate, friendly guidance.

Resolved. I merged the latest main into this branch and fixed the conflict in .github/workflows/pr-labeler.yml while preserving the auto-generated-content warning logic. Addressed in commit 103acea.
