About Fleet's instant ledge slowfall bugfix#1842

The recent bugfix made it so it’s not possible to enter float from ledge by simply releasing ledge and inputting jump.
I think this change isn’t very good:
First, there was already plenty of ways to avoid the instant ledge slowfall; shorthop, releasing ledge with down, or timing the jump.
To do the instant ledge slowfall, it’s now necessary to use a down and away input to release ledge. Not being able to get slowfall from grab release takes away from the flexibility of instant ledge slowfall, in particular on a stage like Harbor, which allowed floating towards the stage previously.
Additionally, the way it was fixed removed the ability to buffer double jump, aerial and float together on ledge release to slowfall back on stage with an aerial, which gave Fleet unique and interesting ledge options.

Instant ledge slowfall is a little bit unintuitive, but it’s also a liked piece of tech for the Fleet playerbase, and it’s a bummer to see its flexibility reduced that way.
