Sync chef-gem and chef-bin

What does this MR do?

This reverts merge request !7276 (merged) and adds comments to the chef-bin and -gem configs.

chef-bin uses the chef-gem with the same version.

This causes the following warning to be printed on reconfigure:

Infra Phase complete, 0/852 resources updated in 11 seconds
[2023-12-23T19:20:40-07:00] WARN: This release of Cinc Client became end of life (EOL) on May 1st 2023. Please update to a supported release to receive new features, bug fixes, and security updates.
gitlab Reconfigured!

By reverting !7276 (merged), only one chef gem is installed (which is patched for the updated EOL).

Note: 17.10.0 is the latest 17.x version released for both chef and chef-bin (chef-bin 17.10.95 is not yet released and chef 17.10.68 has been yanked).
