✨ Automatically create a branch if it does not exist

[Marigold]

Implements #3584

• Running etlr github/co2_data --export creates a branch with the same name as working ETL branch and commits updated files there.
• If the branch exists, push a new commit. (@pabloarosado's suggestion was to fail, but I think it's pretty safe to add a commit given that we don't overwrite existing ones and we create a PR at the end)
• Prefer GITHUB_TOKEN over OWIDBOT_ACCESS_TOKEN (in the future, we should clean it up and use only a single env)
• Show a link to create a PR from our branch
