Fix type annotation for `_internal_arguments` and `_read_internal_argument`

[cotovanu-cristian]

ConfigurationManager._internal_arguments is annotated as dict[str, str] | None, and _read_internal_argument returns str | None. However, the underlying data comes from json.load(), which deserializes JSON values into their native Python types — booleans, ints, floats, lists, nested dicts, and nulls — not just strings.

File: packages/uipath-platform/src/uipath/platform/common/_config.py

def _read_internal_argument(self, key: str) -> str | None:
    internal_args = self._internal_arguments
    return internal_args.get(key) if internal_args else None

@cached_property
def _internal_arguments(self) -> dict[str, str] | None:
    ...

Problem

The dict[str, str] annotation is too narrow. If the config JSON contains:

{"runtime": {"internalArguments": {"isDebug": true}}}

then json.load() returns {"isDebug": True} (Python bool), but the type system says it's a str. This causes two issues:

1. Misleading to readers — code like self._read_internal_argument("isDebug") is True looks like a bug (comparing str | None to True can never succeed), even though it works correctly at runtime.
2. Type checkers would flag downstream is True comparisons as always-False, since the declared return type is str | None.

Suggested Fix

Widen the type annotations to reflect what json.load() actually returns:

from typing import Any

def _read_internal_argument(self, key: str) -> Any:
    ...

@cached_property
def _internal_arguments(self) -> dict[str, Any] | None:
    ...
