There is already a rule. Perhaps the rule can be reused.

This rector needs rewriting. Parent is no longer available by default, so we need to rearcitect this, see https://getrector.com/blog/rector-017-using-scoped-traverse

think something like:

1. Add betternodefinder in constructor (public function __construct(protected BetterNodeFinder $betterNodeFinder){})
2. Match on class method probably (Node\Stmt\ClassMethod::class)
3. Then use $stmts = $this->betterNodeFinder->find($node, FuncCall::class); i think to find if t() is used
4. Use the context of the class to find out if the class has a $this->t(...) availabe. This might neem swithcing with 3, it might be faster that way to first see if we have a t function available, then if so see if it is uses wrongly?
5. Make the change to the functioncall.
