DID Indy Resolver can not resolve Indy DID with additional namespace input

[hviet2603]

Hello development team,

As the title described, indy dids with namespace input e.g. did:indy:example:WRfXPg8dantKVubE3HX8pw seem not to be resolved by the Indy resolver.

I think the regex in messaging/valid.py does not match:

class IndyDID(Regexp):
    """Validate value against indy DID."""

    EXAMPLE = "did:indy:sovrin:WRfXPg8dantKVubE3HX8pw"
    PATTERN = re.compile(rf"^(did:(sov|indy):)?[{B58}]{{21,22}}$")

    def __init__(self):
        """Initialize the instance."""

        super().__init__(
            IndyDID.PATTERN,
            error="Value {input} is not an indy decentralized identifier (DID)",
        )

The pattern is also later used in building the document and submitting Indy VDR requests.

Did indy with namespaces is unfortunately not supported. This example needs to be updated. There's been more work to get away from indy than add namespace support for it in acapy.

There's is a public repo for a plugin that supports it created by Indicio https://github.com/Indicio-tech/did-indy-py.
