fix: incomplete type hint for Regex pattern

[xcrong]

Beanie's Regex Class can use re.Pattern[str] as pattern. In the background, bson.regex.Regex 's .from_native method support it. So I add it to type hint.

In exist tests, we also can see that:

beanie/tests/odm/test_encoder.py

Lines 49 to 55 in 53123ce

	async def test_encode_regex():
	raw_regex = r"^AA.*CC$"
	case_sensitive_regex = re.compile(raw_regex)
	case_insensitive_regex = re.compile(raw_regex, re.I)
	assert isinstance(Encoder().encode(case_sensitive_regex), Regex)
	assert isinstance(Encoder().encode(case_insensitive_regex), Regex)

hey, I can't understand the change, should we change it to:

        ...
        pattern: Union[AnyStr, re.Pattern[AnyStr]],
        options: Optional[str] = None,
        ...

No because pymongo will raise an error ($regex has to be a string)
pymongo can only accept a string or a re.Pattern

Okay, it took us a while, but we finally got there. Looks good to me now.
