Upgrade Solr version for ckan-solr9 to solve security vulnerabilities

[drentawc]

I was wondering if the ckan-solr:2.10-solr9 docker image could be updated to use the newest Apache Solr version (9.7.0) to solve two active security vulnerability found here: https://nvd.nist.gov/vuln/detail/CVE-2024-45216 & https://nvd.nist.gov/vuln/detail/CVE-2024-45217.

Apache Solr has upgraded their own base docker image (latest, slim, and 9) to use this new version rather than the 9.5.0 version that the ckan-solr9 is using.
