File Entity Browser - update short description

Tagged as DrupalCon Lille 23 and Novice

We, the mentoring team, are triaging issues for first time contributors at DrupalCon Lille and I think this is a good issue for the contribution day.
We are reserving this issue so please don't work on this issue if you are not at DrupalCon Lille. You can continue the work when the event is over.

Link to the detailed page of the module added to the issue summary.

Updated the issue summary, suggesting a couple changes to the description. First, I removed the repetition of the module name, something I've seen done in other proposed descriptions, and the name was inaccurate here anyway. Second, I removed mentions of the File Entity and Media Entity modules; while they're noted in the module's description, I'm not sure how directly relevant they are these days to the module's utility, especially given that Media Entity has since been replaced by the core Media module. Definitely not opposed to further adjustments, though.

I think the proposal sounds clear and simple.
