Add labels to BP Group Settings radio buttons

[tw2113]

Instead of making users click the radio buttons directly, allow clicking the associated text as well. Also helps with accessibility

Awesome, this looks like a good fix.

Your patch also demonstrates that our use of <label for="group-status"> is incorrect. Labels go with individual controls, not entire sets. We should wrap these options in a <fieldset> and then apply a <legend> instead of a top-level label. tw2113, you fancy updating your patch with that change?

Sure, I can give that a go this weekend. I want to make sure the markup is applied correctly. It's been a little while since I used <legend> afterall.

Adds fieldset and legeng to already supplied label fix.

I got ambitious :D

In 8013:

Reconfigure markup for radio buttons on group admin meta boxes

<label> elements should be applied to the individual radio buttons rather
than the entire set, for better accessibility and standards compliance.

The old top-level label is replaced by a fieldset and legend.

Fixes #5437
