Setup GitHub Actions for README auto-deployment to GitHub Pages

[AnthonyByansi]

Hi @fhinkel

This pull request adds a GitHub Actions workflow to automatically publish changes from the README.md to GitHub Pages. The workflow is triggered on pushes to the main branch that include changes to the README.md. It converts the README.md into an index.html and deploys it.

Changes:

• Created .github/workflows/deploy.yml to define the GitHub Actions workflow.
• The workflow checks out the code, converts the README.md to index.html, and deploys it using peaceiris/actions-gh-pages.

Resolves #22

Hi @AnthonyByansi, what is the goal of this PR?

Hi @sarah-yo
Well, as you might have noticed, the repo site is not updated automatically, it only reflects changes for the initial deployment.

As spotted by #22

@AnthonyByansi understand. However, this can be done using a first party Github action now rather than a third party one (like this example here: https://github.com/tonybaloney/vscode-pets/blob/main/.github/workflows/docs.yml , please can you update this to use native GH actions?

@AnthonyByansi can you please make sure the job had appripriate permissions, I think you need a statement along the lines of this:

# Sets permissions of the GITHUB_TOKEN to allow deployment to GitHub Pages
permissions:
  contents: read
  pages: write
  id-token: write

# Allow one concurrent deployment
concurrency:
  group: "pages"
  cancel-in-progress: true
