fix(vim.pack): error if git is not installed

[mrcjkb]

Problem

vim.pack.get() will throw an error if Git is not installed (Neovim 0.12.1).

Solution

Wrap the vim.pack plugin detection in a pcall.

i'd rather the vim.pack.get is pcalled and and the error is returned in a warning

Done. I've also passed in { info = false } to prevent it from trying to use Git to get additional info that isn't used by catppuccin.nvim.
