Change Git Workflow

[ChristianChiarulli]

We should adopt a more standard way of managing branches and releases, as well as nightly builds

AC:

• rolling is merged into master
• all new PRs will be merged to master
• master is the "nightly" build
• releases will be frozen to their own branches titled release-vX-neovim-0.Y (where X is the current LunarVim version and Y is the compatible neovim version)

Hello please Assign me to work on this

[gnmearacaun]

Is there an automated way for the latest release to get fixes for breaking changes from plugins? If you need someone to maintain Release to apply those breaking changes I can be that person. For example, this was fixed in Nightly and is required by Release version #3457
