[space-infix-ops] Ignored around field initializers

[dandv]

I've setup my project with the recommended settings. ESLint rules defined in .eslintrc.cjs are triggered correctly, e.g 'space-infix-ops': 'error' triggers on const first='John'. What I don't see happen is that rule triggering on field initializers, but if I understand correctly the marriage between TypeScript and ESLint, this rule should be implemented separately; however, I haven't found a relevant rule under the supported rules, so maybe one should be made and hence the title of my bug is incorrect? Apologies for the confusion.

Repro

{
  "rules": {
    'space-infix-ops': 'error'
  }
}

class Person {
  first='John'
}

Expected Result
ESLint: Operator '=' must be spaced.(space-infix-ops)

Actual Result
Only the obvious warning, 1:7 warning 'Person' is defined but never used @typescript-eslint/no-unused-vars.

Yeah, ESLint doesn't support class properties yet, because they've not progressed far enough in the spec process.

Happy to accept a PR to add an extension rule.

[FDIM]

I've just bumped into this inconsistency regarding assignment and would like to tackle this issue.

@bradzacher Do you agree that space-infix-ops in this repo should be updated to cover property initialization ? I think it should.
