feat(auto-save-nvim)!: swap to okuuva repo

[ALameLlama]

Closes #1233

📑 Description

Updates to use actively maintained okuuva repo, I also needed to update the way the callbacks work. These are currently broken since it's using autoformat_enabled instead of autoformat

Review Checklist

Does this PR follow the [Contribution Guidelines](development guidelines)? Following is a partial checklist:

Proper conventional commit scoping:

• If you are adding a new plugin, the scope would be the name of the category it is being added into. ex. feat(utility): added noice.nvim plugin

• If you are modifying a pre-existing plugin or pack, the scope would be the name of the plugin folder. ex. fix(noice-nvim): fix LSP handler error

• Pull request title has the appropriate conventional commit type and scope where the scope is the name of the pre-existing directory in the project as described above

• README is properly formatted and uses fenced in links with <url> unless they are inside a [title](url)

• Entry returns a single plugin spec with the new plugin as the only top level spec (not applicable for recipes or packs).

• Proper usage of opts table rather than setting things up with the config function.

• Proper usage of specs table for all specs that are not dependencies of a given plugin (not applicable for recipes or packs).

I'll still need to do a little more testing, but this should be a drop in replacement to the old callbacks and actually work since before they used the wrong vim options

@Uzaaft Done 🫡. Moved to use astro core autocmds and everything still seems to be working

I also might need to update the title of this PR to include that it's a breaking change.

the forked repo is a drop-in replacement if it's just the defaults but if people have extended it, it might break things
