[YOURLS] Bump `yourls-python` to 1.2.3

[Injabie3]

Description of the changes

This PR fixes an issue where the [p]yourls stats command would error out. The root cause is in the call to YOURLS' stats method: when the limit value is more than the number of shorten URLs, it would raise a KeyError. This call is made by cmdStats in cog yourlsClient (which basically means [p]yourls stats) which always specifies a limit of 3.

This resolves #641 .
