feat(repo_ref)!: align maintainers tag to nip34 style

nip34 specifies that repo event tags with multiple values wuch as
"relays" and "web" use theformat:

`["tag", "item", "item"...]`

instead of:

```
["tag", "item"],
["tag", "item"],
```

this update also adds clarity. it is not obvious that using a p tag
is intended to make the pubkey a co-maintainer.

BREAKING CHANGE: format of maintainers tags in repo events has
changed to reflect nip34 style and ngit will not detect the old
format
