Description

arca.live uses a hashtag number identifier as people can have the same usernames. However gallery-dl does not see these userpage links as a valid URL for the arcalive extractor

example:

User: ㅇㅇ#10727074

User url: https://arca.live/u/@%E3%85%87%E3%85%87/10727074

Trying to run gallery-dl on this url results in:

[gallery-dl][error] Unsupported URL 'https://arca.live/u/@%E3%85%87%E3%85%87/10727074'

Research direction
Investigate the arcalive extractor in the gallery dl source code, likely in `extractor/arcalive.py`. The current URL pattern does not match URLs with a numeric suffix after the username. Modify the regex to accept the format `https://arca.live/u/@username/number`. Also check if the extractor needs to handle the response for such user pages to extract content. Look at existing tests for the extractor and add a test case for this URL pattern.
