ForwardRef not unwrapped for inner quoted types in arguments

Expected behavior

ForwardRef wrappers to be removed from argument type annotations, as per 8702f62.

Actual behavior

For arguments, the wrapper is removed only if the entire type is quoted. When a quoted reference forms part of a larger type (e.g. Optional["MyClass"]), the wrapper persists in the formatted annotation.

Return types are however correctly parsed in either style.

Example

from typing import Optional

def all_quoted(arg: "Optional[MyClass]") -> "Optional[MyClass]":
    pass

def min_quoted(arg: Optional["MyClass"]) -> Optional["MyClass"]:
    pass

This produces the following, with ForwardRef wrapping the argument to min_quoted but not its return type:

Functions

all_quoted(arg: Optional[MyClass]) ‑> Optional[MyClass]

min_quoted(arg: Optional[ForwardRef('MyClass')]) ‑> Optional[MyClass]

Additional info

• pdoc version: 0.9.2

No source file or test is named. Reproduce the all_quoted and min_quoted examples, then trace pdoc's argument-annotation parsing and formatting path; done means inner quoted references no longer display as ForwardRef while the return annotations remain unchanged.
