[apache] Add type hints to apache obj and http_01 for mypy --strict (#10154)

```
$ mypy --strict certbot-apache/certbot_apache/_internal/http_01.py 
Success: no issues found in 1 source file
$ mypy --strict certbot-apache/certbot_apache/_internal/obj.py 
Success: no issues found in 1 source file
```

PEP 526 says to declare types of unpacked tuples beforehand:
https://peps.python.org/pep-0526/#global-and-local-variable-annotations.
Could have just declared it in apache, but improved the acme return type
while I was at it.

Once again, `typing.Pattern` is deprecated in favor of `re.Pattern` so
changing that while parametrizing the type
