Expose Solr port for dev

[pdurbin]

What this PR does / why we need it:

This useful when trying to reload Solr after adding a metadata block and running update-fields.sh.

See https://guides.dataverse.org/en/6.9/container/running/demo.html#additional-metadata-blocks

My workaround is to exec into the Solr container first:

pdurbin@beamish dataverse % docker exec -it dev_solr bash
solr@solr:/opt/solr-9.8.0$ curl "http://localhost:8983/solr/admin/cores?action=RELOAD&core=collection1"
{
  "responseHeader":{
    "status":0,
    "QTime":479
  }
}solr@solr:/opt/solr-9.8.0$
