Feature request: add codeberg equivalents of the github functions

[rgayler]

Many researchers are currently looking to minimise their dependencies on US corporate controlled infrastructure – including GitHub and GitLab. Codeberg is a popular European based alternative to US-based services such as GitHub and GitLab. As a non-profit community-led effort for free and open source projects Codeberg aligns with the values of many researchers and rstats users.

I think having Codeberg equivalents of the {usethis} GitHub functions would simplify the adoption of Codeberg by the segment of the rstats user base that finds {usethis} generally helpful (like me).

Adding other suggestions that came in through a recent discussion on mastodon

usethis::pr_* family

I think these functions might even be able to re-use the same API. These would already be suitable for codeberg if these functions didn't assume GitHub, but instead looked at the remote to determine and/or offer the choice of platform where you want to open the PR.
