feat: add support for new LSP config API in Neovim 0.11+

[umutondersu]

Summary

• Added support for the new LSP configuration API introduced in Neovim 0.11+
• Maintains backward compatibility for Neovim 0.10 and below

[ro0gr]

Kickstart.nvim targets only the latest 'stable' and latest 'nightly' of Neovim.

Do we really need backward compatibility with Neovim 0 10? I'd consider going with a lighter, happy-path solution. Since the project mainly targets newcomers and servers educational purposes, they'd likely prefer to avoid dealing with legacy approaches.

I think that would be the right approach as well. The reason I intended to maintain backwards compatibility is that some parts of the code is still trying to maintain 0.10 like the client_supports_method. Depending on the others reaction I would also be in favor of removing it.

[umutondersu]

There is also the problem new syntax not supporting all lsp configs. For example tailwindcss requires the old setup. Could be a good idea to delay this until most lsp configs migrate.

• This setup config does not clash with blink.cmp so in that sense It should be okay.
• I would be able to support this in an ongoing basis
• I think using the native way would provide a better experience for newbies but that's up to debate

In my opinion, we shouldn't bother with backwards compatibility since Kickstart is mostly aimed at beginners who will download the latest version of Neovim as per the instructions in the repo readme

I have removed backwards compatibility and added useful comments for LSPs that still require the old setup

[umutondersu]

Messing around with this and found that this will not respect the lsp_format = "fallback" option in the conform.nvim config. To replicate:

1. comment out the stylua formatter line from conform.nvim config

2. save and reload neovim

3. overindent a line or any other formatting change

4. write file

For me it did not fallback on the lua_ls server for formatting.

I couldn't replicate the issue. I do not think it would be related to these changes as conform.nvim does not use an LSP. In any case If you could check your conform logs by using :ConformInfo It could reveal more info about the issue.
