Documentation of `pre_comment_content` declares wrong variable type information

[meitar]

Super simple, but I just noticed that the documentation for the pre_comment_content filter says the filter returns an int when in fact it returns a string.

Trivial patch attached.

[meitar]

Correct type information for filter hook return value.

@meitar Thanks for the patch, could you update it to include the two filters above and below pre_comment_content

That is in that same wp_filter_comment() function both the filters pre_comment_user_agent and pre_comment_user_ip below should also both be string

[meitar]

Correct variable type information for additional two neighboring filters.

:) LOL, tunnel vision. I didn't event notice those because tunnel vision on this project, I don't need those fields. But yes, I added a new patch. Thanks for catching those.
