option to specify the path to `pdm`

[DetachHead]

i have pdm pinned and installed within my project using pyprojectx, so it would be nice if i could tell the action to use that version instead of the one in the setup-pdm action

something like a pdm-path option would be great:

jobs:
  update-dependencies:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v5
      - name: Update dependencies
        uses: pdm-project/update-deps-action@main
        with:
          pdm-path: .pyprojectx/main/pdm
