There's a regex pattern in https://github.com/vsoch/oci-python/blob/master/opencontainers/distribution/reggie/defaults.py#L17
that doesn't properly escape the `/` characters. It's unclear to me at the moment what's changed (other than python updates) have have caused this to be an issue in particularly for [Authentik](https://github.com/goauthentik/authentik/issues/8936).
I'm not quite clear on the preferred contribution method here, but I'll at least fork and create a PR for this change and see if that's helpful.
I dont think the PR fully fixes the issue, at least its still raising a warning in python 3.12.4
I suppose the fix would be using `r""` instead of escaping it:
```
>>> from re import *
>>>
>>> # old regex
>>> compile("http[s]?://(?:[a-zA-Z]|[0-9]|[$-_@.&+]|[!*\(\),]|(?:%[0-9a-fA-F][0-9a-fA-F]))+")
<stdin>:1: SyntaxWarning: invalid escape sequence '\('
re.compile('http[s]?://(?:[a-zA-Z]|[0-9]|[$-_@.&+]|[!*\\(\\),]|(?:%[0-9a-fA-F][0-9a-fA-F]))+')
>>> # new regex
>>> compile("http[s]?:\/\/(?:[a-zA-Z]|[0-9]|[$-_@.&+]|[!*\(\),]|(?:%[0-9a-fA-F][0-9a-fA-F]))+")
<stdin>:1: SyntaxWarning: invalid escape sequence '\/'
re.compile('http[s]?:\\/\\/(?:[a-zA-Z]|[0-9]|[$-_@.&+]|[!*\\(\\),]|(?:%[0-9a-fA-F][0-9a-fA-F]))+')
>>>
>>>
>>> # fixed
>>> compile(r"http[s]?://(?:[a-zA-Z]|[0-9]|[$-_@.&+]|[!*\(\),]|(?:%[0-9a-fA-F][0-9a-fA-F]))+")
re.compile('http[s]?://(?:[a-zA-Z]|[0-9]|[$-_@.&+]|[!*\\(\\),]|(?:%[0-9a-fA-F][0-9a-fA-F]))+')
>>>
```
