Regenerate bindings

[segevfiner]

Still need to update the GitHub Actions workflows to produce prebuilds for Node.js, etc.

Checklist:

• All tests pass in CI.
• The script/parse-examples passes without issues.
• There are sufficient tests for the new fix/feature.
• Grammar rules have not been renamed unless absolutely necessary.
• The conflicts section hasn't grown too much.
• The parser size hasn't grown too much (check the value of STATE_COUNT in src/parser.c).

You should either remove the existing swift bindings or the generated ones.

superseded by #312, sorry there were just a lot of little things to fill in/update

[segevfiner]

That's fine. I submitted this to try and coax some progress on updating the grammars.

Yeah I'm getting to them now, sorry about that
