Define standards for describing LSP servers.

[PerilousBooklet]

As suggested by Guldoman, we should define a standard descriptive convention for LSP server entries, to keep them neat and tidy.

For the naming convention we could do something like name_ls ( svelte_ls, tailwindcss_ls, ...).

For the description, we could write something like the following:

---# language_name - lsp_server_name
--- __Status__: Untested/Works/Works Partially
--- __Site__: https://github.com/user/lsp_server_name
--- __Installation__: ...
--- __Note: ...

The Perl entry is a good example:

---# Perl - Perlnavigator
--- __Status__: Works
--- __Site__: https://github.com/bscan/PerlNavigator
--- __Installation__: `paru -S perlnavigator`
