numVersionBuckets Settings Obsolete as of solr 9.8

Setup

• Solr version: 9.8+

• Search API version: 8.x-1.38
• Search API Solr version: 4.3.10
• Configured Solr Connector: Basic Auth

Issue

I'm seeing this warning in my Solr admin log after upgrading to Solr 9.9.0:

numVersionBuckets is obsolete

Looking at the Solr documentation (https://github.com/apache/solr/blob/main/solr/solr-ref-guide/modules/upg...), we see:

In solrconfig.xml, the numVersionBuckets and versionBucketLockTimeoutMs settings are now obsolete and ignored; a warning will be logged if specified.

This is what's in the solrconfig.xml file:

<int name="numVersionBuckets">${solr.ulog.numVersionBuckets:65536}</int>

This line should be removed for compatibility with solr 9.8+.
