Support and ignore warnings for deprecated /extend in plugin URLs

[netweb]

Looking through the #polyglots-warnings I came upon this warning:
​https://wordpress.slack.com/archives/polyglots-warnings/p1443027038000432

New translation warning for Plugins - Regenerate Thumbnails - Development Readme (trunk) in Hebrew #he:
​*Warning:*​ Expected <a href="http://wordpress.org/extend/plugins/regenerate-thumbnails/screenshots/">, got <a href="http://he.wordpress.org/extend/plugins/regenerate-thumbnails/screenshots/">.
*Original:*​ See the <a href="http://wordpress.org/extend/plugins/regenerate-thumbnails/screenshots/">screenshots tab</a> for more details.
​*Translation:*​ למידע נוסף ראו <a href="http://he.wordpress.org/extend/plugins/regenerate-thumbnails/screenshots/">צילומי מסך</a>.

The string had been translated
from: http://wordpress.org/extend/plugins/regenerate-thumbnails/screenshots/
to: https://he.wordpress.org/extend/plugins/regenerate-thumbnails/screenshots/

It should be: https://he.wordpress.org/plugins/regenerate-thumbnails/screenshots/

i.e. It should NOT have included the /extend/ component in the URL.

There are 2 parts to this ticket:

1) Support and/or ignore warnings that include extend in the URL when related to plugin URL's

2) A systems request to add redirects for localised plugin URL's containing extend

• Redirect https://he.wordpress.org/extend/plugins/regenerate-thumbnails/screenshots/ to https://he.wordpress.org/plugins/regenerate-thumbnails/screenshots/

Yes, it was me. I've been translating "import plugins" to hebrew and it seems like many import plugins (by wordpressdotorg) use the old plugin URL structure with http:// and /extend/plugins/.

We should find all the plugins that use /extend/plugins/ and update them.

Those warnings are rather rare, it's just a warning which can be dismissed. I don't think we have to make any adjustments here.
