"Abstract classes" test fails on master branch + how can I help?

[mjambon]

Hey @maxbrunsfeld and team + @resolritter,

I see that @resolritter has made many contributions in the last quarter, thank you, this will be of great value to us in semgrep! I would like to help make further progress as well. I noticed the following:

• the master branch fails to pass the test "Abstract classes" despite using a recent tree-sitter-javascript.
• several PRs made by @resolritter would be very valuable once merged but haven't been reviewed yet (Fix type parameter parsing on call expressions #115, Support "infer" types #124, Support more of the export syntax #125, Fix ambiguity between function signature and function declaration #126).

I can help with any of these, I have a couple of days. Please let me know if there's something I can be most helpful with. Otherwise I'll start with looking into the broken build/test.

Martin

#129 should fix this.
