Refactor GitHub Actions workflow to deploy Javadocs without committing to the repository

- Removed the `commit-javadoc` job to prevent committing files to the repository.
- Updated the `build-javadoc` job to upload Javadocs as artifacts.
- Modified the `deploy-javadoc` job to deploy using the uploaded artifacts.
- Updated README to reflect the new deployment process.

@@ -9,8 +9,6 @@ This repository uses a custom GitHub Actions workflow [`build-and-deploy-javadoc
 
 The workflow clones the `processing/processing4` repository, gets the commit corresponding to the latest release, builds the Javadocs using `ant`, and copies the generated files to the `/docs` directory of this repository. The updated Javadocs are then committed and pushed to the `gh-pages` branch.
 
-We've set "Deploy from branch" in the repo settings to trigger on push to the `gh-pages` branch. Every time the `build-and-deploy-javadoc.yml` workflow completes, it will trigger a deploy to GitHub pages.
-
 The workflow is triggered every Monday at midnight (UTC). A maintainer can manually trigger the workflow if needed.
