Plugin submission: Improve "Review status" message to authors.

[frantorres]

After adding a new plugin, authors can check the status of the submission at ​https://wordpress.org/plugins/developers/add/

When the submission is in "Pending" status (this is the status it changes to when a reviewer initiates a review) authors see this message there:

Review status: Being Reviewed — This plugin is currently waiting on action from you. Please check your email for details.

The review process requires several email exchanges in which either the reviewer waits for the author's reply or the author waits for the reviewer's reply.

Some authors have been feel confused by this message when they are waiting for the reviewer's response, as it states that is "waiting on action from you" so they think they missed an email.

Also, some authors had troubles finding the initial email the reviewer sent to them. Sometimes it goes to spam and they need to check that manually.

The proposal is to change this message to:

Review Status: In Review — The team sent you an email <Plugin changed to pending timediff> with the subject "[WordPress Plugin Directory] Review in Progress: <Plugin name>". Please check it and continue to reply to our emails regarding necessary changes (if you haven’t seen that email, please check your spam)

Being:

• <Plugin changed to pending timediff>: The timediff to the date when the plugin changed to "Pending" status (this date is not the same to the updated date, so might need a new meta).
• <Plugin name>: The current plugin name on the repository (the_title)

Example:

Review Status: In Review — The team sent you an email 6 days ago with the subject "[WordPress Plugin Directory] Review in Progress: Hello Dolly". Please check it and continue to reply to our emails regarding necessary changes (if you haven’t seen that email, please check your spam)

This was partially implemented as part of [13116].

There are two states that can be shown:

Being Reviewed &#8212; This plugin is currently waiting on action from you. Please check your email for details.

Or, if we've found the review email for the plugin, and it's open with the last response from the author, this:

Being Reviewed &#8212; We've got your email. This plugin is currently waiting on action from our review team.

Extending that to show the actual email details when it's waiting on them and we know the review email (which we don't always) is possible.
