Update setup instructions

[gwennlbh]

• Since we have proper lspconfig, get rid of the ugly autocmd thing (also see Simplify language server startup #9)
• Mention astronvim support (see feat(pack): add hyprland config file language support AstroNvim/astrocommunity#1063)
• Mention Mason LSPConfig support (see feat: add hyprls mason-org/mason-lspconfig.nvim#428)
• Setup binaries building infra through goreleaser
• Mention Nix support hyprls: init at 0.2.0 NixOS/nixpkgs#323392

By the way, it would be interesting to bundle binaries in the releases page, so the integration with Mason could be streamlined. I wanna try hyprls, but since I don't use Go myself, the process is slightly more annoying, since I have to use my system's package manager to install Go and then build from source.

Yeah including built binaries with releases would be nice, I'll add a task for that

If you want any help with the Nix part, just ask. I can also help adding a flake.nix in the repository to help with development and for people to be able to test the latest commit.

Also, you might be interested in using a badge in the readme to show which repositories package your program, like repology's one: https://repology.org/project/hyprls/badges.

thx for the suggestion! although unless this gets distributed on more package managers, a repology badge is kinda... weird haha

would totally merge a pr that adds a flake.nix though!
