Update to current parley main

[waywardmonkeys]

This updates to the version using the updated objc2 and binding crates for Fontique.

It also has a minor API change.

Obviously I'm not super happy about an ugly boolean parameter appearing here. For reference, it seems to be from linebender/parley#241, meaning whether we align when overflowing.
The lack of tests in that PR to make it more comprehensible isn't ideal...

In this case:

1. I agree that false maintains the same behaviour here. I think that true would maybe be a better default, but that should be a follow-up
2. I think that Replace boolean option in Layout::align with AlignmentOptions Struct parley#247 should block parley 0.3 (cc @tomcur); the fact that every use in Make alignment when free space is negative configurable parley#241 needed to be documented with the parameter name as a comment strongly supports this...

Yes, that issue is blocking 0.3. Nico opened a PR fixing it yesterday: linebender/parley#278.

I believe false (start-alignment for lines that overflow) is what web does, and currently that's the planned default for the AlignmentOptions introduced in Nico's PR.

@DJMcNab I've removed this from the auto-merge because I had to update a single screenshot test. @tomcur You might want to take a peek just to be sure all is well.

@waywardmonkeys It looks to me like the old version is including trailing whitespace in the width of the line for the purposes of alignment, and the new version is ignoring. If so, then I believe the new version is correct. Eyeballing it, the text looks more centered in the new screenshot.
