Coding Standards: Restore correct regex formatting in `dbDelta()`.

An earlier regex for normalizing index definitions disables the PHPCS check for extra padding in order to keep a more readable indentation. However, this was missed for index columns regex.

Follow-up to [37583], [42228], [42249], [42343].

See #55647.
