Problems with clone on startup with git host in same Caddyfile

I am using Caddy for proxying to gitea and providing static file hosting from a directory. I now want to auto-deploy a website using this plugin.

Caddyfile looks like this:

```
git.bar.com {
proxy / localhost:3000
}
blog.bar.com {
root /var/www/foo2
git {
repo https://git.bar.com/...
}
}
```

Now the startup fails as the initial clone can not reach the git Server as the caddy serves this itself. Maybe it is possible to delay the clone, ignore errors or deactivate that behaviour? All three are possible solutions.

EDIT: Didn't want to add a new issue for this: Does it serve the .git folder? Or do I need to use the internal directive to hide it?

EDIT 2: Also mentioned in #102, #79 and #85
