Simplify setup documentation

If you like, you can directly deep link to the "Generate a token" page and even preset the scopes, for example

https://github.com/settings/tokens/new?scopes=repo

That way you don’t need to describe all the separate steps at https://status-checks.netlify.com/docs/getting-started/setup#steps

Just wanted to mention it, up to you :)

Start at the setup documentation's steps section: https://status-checks.netlify.com/docs/getting-started/setup#steps. Replace the separate token-generation instructions with a direct link to GitHub's Generate a token page using the suggested repo scope, then verify that the setup flow remains understandable and the link works.
