Allow Splunkbase or Private Apps in Versioning Checking

[pyth0n1c]

Only ESCU is supported at this time for enforcing the new Versioning Checks.
We should consider if we want to support:

1. Other apps on Splunkbase; and
2. Private apps that are not on Splunkbase

See the following discussion in the PR which adds Versioning Enforcement: https://github.com/splunk/contentctl/pull/280/files#r1752846568

We will also need to check for different comments in the savedsearches.conf file based on the name of the app: https://github.com/splunk/contentctl/pull/280/files#r1752740324
