Bogdan Grigoruță d1bc6fca71 feat(health): list attached buffers in LSP report #23561
Problem:
Users using `vim.lsp.start` directly (instead of nvim-lspconfig) need
more visibility for troubleshooting. For example, troubleshooting
unnecesary servers or servers that aren't attaching to expected buffers.

Solution:
Mention attached buffers in the `:checkhealth lsp` report.

Example:

    vim.lsp: Active Clients ~
    - clangd (id=1, root_dir=~/dev/neovim, attached_to=[7])
    - lua_ls (id=2, root_dir=~/dev/neovim, attached_to=[10])
