feat(lang/fsharp): add F# support to omnisharp extra (#6538) 
## Description
Extend the existing C#/VB setup to support F# development with
formatting, LSP, and debugging integration.

- Extend recommended filetypes and roots to include F#
- Ensure Treesitter installs the `fsharp` parser
- Add Fantomas formatter in none-ls and Conform
- Ensure Mason installs fsautocomplete and fantomas
- Extend DAP configurations to include `fsharp`

⚠️ For debugging/neotest to work, this PR should be merged together with
[#6540](https://github.com/LazyVim/LazyVim/pull/6540),
which switches Omnisharp extras from `neotest-dotnet` to
`neotest-vstest`.

LazyVim is a Neovim setup powered by 💤 lazy.nvim to make it easy to customize and extend your config. Rather than having to choose between starting from scratch or using a pre-made distro, LazyVim offers the best of both worlds - the flexibility to tweak your config as needed, along with the convenience of a pre-configured setup.

✨ Features

  • 🔥 Transform your Neovim into a full-fledged IDE
  • 💤 Easily customize and extend your config with lazy.nvim
  • 🚀 Blazingly fast
  • 🧹 Sane default settings for options, autocmds, and keymaps
  • 📦 Comes with a wealth of plugins pre-configured and ready to use

⚡️ Requirements

  • Neovim >= 0.11.2 (needs to be built with LuaJIT)
  • Git >= 2.19.0 (for partial clones support)
  • a Nerd Font (optional)
  • a C compiler for nvim-treesitter. See here

🚀 Getting Started

You can find a starter template for LazyVim here

Try it with Docker 
docker run -w /root -it --rm alpine:edge sh -uelic '
  apk add git lazygit fzf curl neovim ripgrep alpine-sdk --update
  git clone https://github.com/LazyVim/starter ~/.config/nvim
  cd ~/.config/nvim
  nvim
'
Install the LazyVim Starter

  • Make a backup of your current Neovim files:

    mv ~/.config/nvim ~/.config/nvim.bak
mv ~/.local/share/nvim ~/.local/share/nvim.bak

  • Clone the starter

    git clone https://github.com/LazyVim/starter ~/.config/nvim

  • Remove the .git folder, so you can add it to your own repo later

    rm -rf ~/.config/nvim/.git

  • Start Neovim!

    nvim

    Refer to the comments in the files on how to customize LazyVim.

There's a great video created by @elijahmanor with a walkthrough to get started.

@dusty-phillips wrote a comprehensive book called LazyVim for Ambitious Developers available for free online.

📂 File Structure

The files under config will be automatically loaded at the appropriate time, so you don't need to require those files manually. LazyVim comes with a set of default config files that will be loaded before your own. See here

You can add your custom plugin specs under lua/plugins/. All files there will be automatically loaded by lazy.nvim
