Create a short description for the Security Kit project

Worked on at DrupalCon Pittsburgh.

Updating the short description to meet length standards.

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.

I'm working at this as part of DrupalCon Lille 2023 contribution day.

Updated the suggestion, to make it a bit more readable.

I find the latest proposed solution good.
