Install hook fails to find a match poetry-core

When building a charm from master branch of mysql-router's charm, we're greeted with an install hook failure on both Focal and Jammy deployments.

This looks identical to #1989327 (Mysql-innodb-cluster charm) and #1989669 (Neutron api OVN plugin charm)

Add poetry-core to the wheelhouse.txt fix the issue as tested on both Focal and Jammy deployment.

Here some logs of the install hook error :
