fix: wrong number of $accepted_args on add_filter() calls

[justlevine]

What?

This PR fixes several instances of the wrong number of $accepted_args being passed to add_filter(), so the match the correct number of args taken by their callbacks.

As the correct $accepted_args and $priority are the defaults once corrected, the explicit args have been removed entirely.

Why?

While this issue was surfaced by PHPStan (via #66693) it can be remediated independently as part of #66598

How?

Yes, level 0 problems must be fixed.

I consider applications with level 4 problems broken.

I think we can just omit $accepted_args when the value is one. It's the default value for hooks.

I think we can just omit $accepted_args when the value is one. It's the default value for hooks.

Perhaps, but figured I'd match the existing patterns e.g.

gutenberg/lib/block-supports/block-style-variations.php

Line 278 in ee1039a

add_action( 'wp_enqueue_scripts', 'gutenberg_enqueue_block_style_variation_styles', 1 );

[Mamaduka]

The 1 in that example is $priority and not the $accepted_args. In any case, it was a minor nitpick, nothing blocker for this PR.

@gziolo / @Mamaduka apologies, I thought I pushed this back in november 😅
