Fix return type

[roxblnfk]

Looks like this return type doesn't work well

support/src/Factory/WorkflowStub.php

Line 78 in b9ab40b

* @return ($type is class-string ? T|WorkflowProxy : WorkflowStubInterface)

If use of documentation:

Psalm documentation:
(https://psalm.dev/docs/annotating_code/type_syntax/conditional_types/)

Conditional types have the form:

(<template param> is <union type> ? <union type> : <union type>)

Current implement:

IDE don't undestand complex templates condition..

But if we rewrite this code

I think it will be better to rewrite the code and separate stub and proxy factories into different functions. It's a bad thing when different interfaces are return depending on input type

[roxblnfk]

It will be rewritten after temporal sdk 2.9 release. There are new concepts discussed around proxies and stubs
