fix(conform-nvim): fix formatters_by_ft definitions

[lucazz]

📑 Description

As requested by @Uzaaft on #1127 #1128, I'm merging all changes in a single PR.

This PR updates stevearc/conform.nvim's setup, addressing the deprecation warning that comes up when opening any yaml file while using the yaml pack:

deprecated[conform]: The nested {} syntax to run the first formatter has been replaced by the stop_after_first option (see :help conform.format).
Support for the old syntax will be dropped on 2025-01-01.

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).

@lucazz I’m about to head to bed so I cant deep dive into it, but based upon the warning you have this seem wrong.

[mehalter]

This is incorrect, all of them should be

{ "prettierd", "prettier", stop_after_first = true }

[lucazz]

Heya @Uzaaft & @mehalter, sure thing added stop_after_first

[Uzaaft]

@lucazz Why did you add it to the places where it's not needed?

[lucazz]

Let me take those out, @Uzaaft I thought it wouldn't hurt to have them in place. hold on

[Uzaaft]

Danke Danke

[lucazz]

Danke Danke

Alright, done and done :-)

[mehalter]

Ok, I think this looks correct now, thanks! Just to clarify why the previous ones were incorrect. The nested structure indicated when to only stop at the first. The ones that were not previously nested indicated multiple formatters so we very much do not want them to stop at the first
