feat: migrate to vim.lsp.config #3659

Problem:
Nvim 0.11 has vim.lsp.config, which mostly replaces the legacy
nvim-lspconfig "framework".

Solution:
Migrate all configs to `lsp/*` variants. The old configs in
`lua/lspconfig/` are "frozen".

The new configs include these changes:
- `commands` field became raw calls to
  `vim.api.nvim_buf_create_user_command` inside `on_attach`.
- `root_dir` became:
  - `root_markers` whenever the file list was simple didn't need to mach `*`
  - if the logic was complicated, or needed to match something like
    '\*.c', it was defined as a vim.lsp.Config `root_dir` callback.
- `on_config_change` became `before_init`. I don't actually know if this
  is the correct approach, but looking around the documentation of
  `nvim-lspconfig` a saw that it was defined as the function that gets
  called as soon as the config have `root_dir`, and so I thought
  `before_init` might be the closest alternative.
- `docs.description` became a luadoc `@brief` docstring.
- `single_file_support = false`?

+-- `textLSP` is an LSP server for text spell and grammar checking with various AI tools.
+-- It supports multiple text file formats, such as LaTeX, Org or txt.
+--
+-- For the available text analyzer tools and their configuration, see the [GitHub](https://github.com/hangyav/textLSP) page.
+-- By default, all analyzers are disabled in textLSP, since most of them need special settings.
+-- For quick testing, LanguageTool is enabled in the default `nvim-lspconfig` configuration.
+--
+-- To install run: `pip install textLSP`
