Any user authenticated on .org should be able to submit user contributed notes

[DrewAPicture]

Not sure what was changed, but it appears as though can_user_post_note() when hooked to comments_open makes it only possible to contribute notes when you're authenticated on .org and/or a member of the DevHub site.

Worked this out with @SergeyBiryukov and he should be following up with a patch.

Introduced in [768].

There's a must_log_in string in the comments.php template, but it's not used because the whole block is not displayed if you're not logged in. Looks like DevHub::can_user_post_note() needs to be removed for it to show up.

In 1687:

developer.wordpress.org: Default to allowing user contributed notes from any user.

• Enable submission of user contributed notes by default.
• Add redirect_to query arg to login link so that user will be redirected back after logging in.
• In [10530-dotorg], a restriction via the 'wporg_devhub-can_user_post_note' hook was removed that prevented non-logged in users from seeing the message that they can log in to submit a note.

Fixes #1094.

I still get a "Sorry, comments are closed for this item" when trying to submit a note.

In 1689:

developer.wordpress.org: Remove restriction that user must be member of blog to post user contributed notes.

Fixes #1094.
