Rewrite the rule with typescript

Having the rule in typescript would be excellent, as it will catch any bugs we may have on hardcoding token types and give us auto completion on things.

We could use JSDoc too, but using typescript will unlock more possibilities, like casting test identifiers to booleans if they are not.

I think using jsdoc would suffice
