chore: update .jshintrc

Changes:
- `esversion: 11` We use bundlers so let's use a modern version of js
- `maxlen: 120` This should be enforced by linters if at all (the rule is
  deprected by jshintrc anyway: https://jshint.com/docs/options/#maxlen)
- `asi: true` Suppress warnings about missing semicolons (it's 2024
  after all)
