Docker pull sphn-connector_connector:1.4.3

Dear all,

we are trying to get the SPHN Connector running on our infra behind a nexus repository manager and it does not transparently allow pulling from a hardcoded URL. I get the following error:

$ docker --version
Docker version 24.0.4, build 3713ee1

$ docker pull registry.dcc.sib.swiss/sphn-semantic-framework/sphn-connector/sphn-connector_connector:1.4.3

Can you please change this or point me to the Dockerfile to build it locally instead?
