The links for installing Earthly get the user stuck in an endless loop.

1. Visit https://github.com/earthly/earthly
2. Click "Installation" (takes you to https://github.com/earthly/earthly?tab=readme-ov-file#installation)
3. Click "installation instructions" (takes you to https://earthly.dev/get-earthly)
4. https://earthly.dev/get-earthly -[REDIRECTS_TO]-> https://github.com/earthly/earthly

And you are back where you started.

You can still download the binary manually from the releases page, but the above might confuse some users into not getting started.
