Comments: Restore global $comment assignment in comment_form_title().

Restores the global `$comment` assignment in `comment_form_title()`, which was mistakely removed in [55369].

As noted in the function's DocBlock:
{{{
@internal The $comment global must be present to allow template tags access to the current comment. See https://core.trac.wordpress.org/changeset/36512.
}}}

Follow-up to [55369].
