fix(auto-save-nvim): disable format on save when auto saving

[mehalter]

📑 Description

Formatting on save with the automatic saving breaks undo because whenever you undo it reformats immediatley. This disables the automatic formatting when buffers are auto saved. It still lets auto formatting work when saving manually with :w for example.

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)

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