[Icon Requests from Feather] `boat` / `ship`

As per #119 and feathericons/feather#631:

@karsa-mistmere I think the left one is not really in the "lucide" style. The left sail of the second one looks a bit too dense i think.

Yeah, you're probably right in both cases, here's a looser version of sailboat:

Suggesting a few modifications:

• If the two sails are distinguished from each other by their size (which means the boat now has a moving direction from right to left), I feel it would be nice to distinguish the front and the rear of the boat as well. The front is pointier, the rear is usually dull or flat.
• I also adjusted the size of the larger sail to have nicer proportions.

SVG is attached as well.
