BP Add-ons Plugin admin tab: stop using buddypress wp.org account favorites to fill this tab

[imath]

Using this way of listing tabs isn't stable enough, we need to think about adding the Add-ons as favorites of the buddypress wp.org account.

We should use the author field of the query_plugins WP.org API endpoint and edit all Add-ons readme.txt to reflect this.

I believe it's very important to be sure to have the BP Classic plugin listed into this tab (as well as BP Attachments), and they are not so far.

I've already created these PRs on Add-ons GH repositories:

• ​https://github.com/buddypress/bp-beta-tester/pull/3
• ​https://github.com/buddypress/bp-attachments/pull/87
• ​https://github.com/buddypress/bp-classic/pull/25
• ​https://github.com/buddypress/bp-rewrites/pull/52
• ​https://github.com/buddypress/bp-blocks/pull/82

I'll add a PR to this ticket about the BP Core Administration change

Update arguments used to query for BuddyPress Add-ons.

I've just tested with the BP Search Block plugin, and it works as expected:

I'll merge all other PRs and update readme.txt on each WP.org repository asap.

Use the author field to query Add-ons via the WP.org Plugin API

All existing Add-ons have been updated so that the contributors: header tag of their readme.txt file has been set to buddypress.

The Request we use to fetch BuddyPress Add-ons in the corresponding Plugin Admin screen will from now on look up for WordPress plugins authored by BuddyPress.

Fixes #8984
