Add labeler

[Fokko]

To add the ability to filter on specific components.

The list of labels is probably not exhaustive, but is a first start.

Shall we also add a workflow that use these labels in this PR?. As suggested in https://github.com/marketplace/actions/labeler

.github/workflows/labeler.yml

name: "Pull Request Labeler"
on:
- pull_request_target

jobs:
  labeler:
    permissions:
      contents: read
      pull-requests: write
    runs-on: ubuntu-latest
    steps:
    - uses: actions/labeler@v5

I'm +1 for adding the sync-labels as well, it sounds like it could be helpful

    permissions:
      contents: read
      pull-requests: write

      with:
        sync-labels: true
