Sergey Biryukov 0768c65310 Coding Standards: Remove unnecessary ignore annotation in wp_kses_hair_parse().
It is perfectly possible to write a commented regex with layout for readability by using the `x` modifier.

As per the manual:
> x (`PCRE_EXTENDED`)
>
> If this modifier is set, whitespace data characters in the pattern are totally ignored except when escaped or inside a character class, and characters between an unescaped # outside a character class and the next newline character, inclusive, are also ignored. This is equivalent to Perl's /x modifier, and makes it possible to include commentary inside complicated patterns.
>
> Note, however, that this applies only to data characters. Whitespace characters may never appear within special character sequences in a pattern, for example within the sequence (?( which introduces a conditional subpattern.

Reference: [https://www.php.net/manual/en/reference.pcre.pattern.modifiers.php PHP Manual: Pattern Modifiers].

This commit rewrites these two regexes to use the `x` modifier and gets rid of the unnecessary `phpcs:disable` comments.

The tests in the `tests/phpunit/tests/db/dbDelta.php` file cover this change.

Follow-up to [42249].

Props jrf.
