• Fix R-universe installation instructions.

Some notes on difference in support based on organizations (to be added to the dev guide?).

• @steffilazerte would we find the help-wanted issues for repositories that have not been transferred? (a bit lazy to ask rather than check 😅 🙏 )
• COC by rOpenSci only visible on pkgdown website.
• we can't help with transferring access to a new maintainer.
• the repository can't be pinned.

Hi @maelle, yes it looks like right now we pull help-wanted issues from the ropensci and ropenscilabs repositories. However, I think we could add in a look at the registry.json in order to add other repository locations (as long as that is where they would be stored).

Thank you! Where should I open an issue to track this?
