Add GitHub Action for publishing the extension CLI (#9542)

This PR adds a GitHub Action for publishing the extension CLI.

When the `extension-cli` tag is pushed, this Action will run, build the
`zed-extension` binary, and upload it to DigitalOcean for consumption.

This will allow us to consume the pre-built binary in the CI for the
extensions repo.
