fix(dependency): esy-skia -> 91c98f6

[glennsl]

This brings in a fix to esy-skia that allows it to build with clang 10.2 on Arch Linux.

For some possibly unrelated reason I'm not able to build revery directly due to a failure building ocamlfind, and despite being able to build Oni2 with this same fix, but I'm submitting this now anyway to see what the CI says.

Ok, looks like there's an issue with OCaml 4.10.2 on my machine, and that Oni2 builds fine because it's pinned to 4.10.0 while the constraint on revery is ~4.10, which then picked 4.10.2 when I touched other dependencies.

I'll continue to investigate this separately and see no reason for that to block this from being merged.

Nice, thanks @glennsl !

I believe this is due to this bug: esy/esy#1171 (it was the reason I pinned Onivim to 4.10.0)

esy@0.6.7 may fix this, as it includes a fix for that particular issue - I haven't tested it yet though.

Testing esy@0.6.7 here: #1035

Ah, yeah that seems likely.

I was already using 0.6.7. @esy-nightly/esy fixed it though, but now esy-harfbuzz fails to build...

error: command failed: './esy/prep.sh' (exited with 127)

None of this affects this PR though, so I'll merge it.
