fix: opam update before lsp upgrade

[mercxry]

Hello 👋

I'm fixing a bug where installing a new version of ocaml-lsp would make opam complain about not being able to find the new version locally, this is because opam update needs to be run first to update the local repositories, so I'm running that command before any installation.

Ugh stylua is complaining, I'll fix it shortly.

I just saw the following in their docs which I don't understand, but which might be a bit problematic if it can't be turned off. Will have to research it a bit more

It will also update any packages that are bound to version-controlled sources.

Hi again, I've not been able to find a resolution to the concern above of this command potentially modifying opam packages installed elsewhere on the system. One of the core principles of mason.nvim is to never touch the file system outside of Mason's root directory (except logs, cache, etc. that dependencies write). I'll go ahead and close this for now but I'd be open if we can resolve it somehow.
