Generates documentation for a Swift package using the swift-docc-plugin.

To use, make sure that your package includes a dependency on the plugin in your Package.swift:

.package(url: "https://github.com/apple/swift-docc-plugin.git", from: "1.0.0"),

Then include the action in your workflow (make sure that a Swift 5.6+ toolchain is on your PATH, on macOS this should be given, but on Linux you may need to first install it e.g. using setup-swift):

- uses: fwcd/swift-docc-action@v1
  with:
    target: YourTarget
    output: ./docs
    hosting-base-path: yourproject
    disable-indexing: 'true'
    transform-for-static-hosting: 'true'

The generated documentation will be in the ./docs folder. If you wish to host your docs on GitHub Pages, check out this tutorial from the official docs.
