Fix Solr probes w/TLS for Solr 9.2+

Currently various versions of Solr 9 cannot be run with TLS in the Solr Operator, because of the way that secure probes are run. Namely, we explicitly invoke SolrCLI, which has changed its location in newer versions. We need to use the `solr api -` command, which will be available in Solr 8.11, so this can only be done when that is the minimum supported version.
