null-ls is end of life

[AndrewWinterman]

The maintainer of null-ls is stepping away from the project, so it might be worthwhile to update this project to integrate with a different lsp protocol.

The project has been continued under a new name.
Its fully compatible so far.
https://github.com/nvimtools/none-ls.nvim

However, afaik the goal is to develop a "real" LSP server fo nushell,
which means, that none-ls is no longer needed.
