create alias berries -> berry

Current tag count:

• berries (414 posts)
• berry (93 posts)

I'm not sure we need a plural "berries" in addition to singular "berry".

If there are multiple berries on the image, then there's at least one, so the tag "berry" would apply anyway.

Several posts with singular "berry" already have multiple berries (post #3629884, post #2860200, post #3272548, etc.)

I previously suggested just deleting both "berry" and "berries" and aliasing them to "fruit" (topic #16978) but most people didn't like that idea.

This bulk update request is pending automatic rejection in 5 days.

The bulk update request #4160 (forum #177262) has been approved by @evazion.

I'll do this for consistency with strawberry / blueberry / raspberry / etc. Although one could argue that it should be plural like grapes because berries normally come in bunches.
