Set up Gitea on this VM by following the exe.dev recipe at https://exe-staging.dev/deploy/gitea.md from top to bottom.

The recipe's example VM name is my-gitea. This VM's name is the output of `hostname`: use it wherever the recipe writes my-gitea. Skip the step that creates the VM; you are on it.

You are done when all of these are true. Check each one yourself:
- Gitea behind exe.dev's [HTTPS proxy](/docs/proxy), on port 8000
- nginx translating `X-ExeDev-UserID` and `X-ExeDev-Email` into `X-WEBAUTH-USER` and `X-WEBAUTH-EMAIL`
- Auto-registration, so any exe.dev user you share the VM with gets a Gitea account the first time they visit

Finish with the URLs I should open.
