[CLOUDP-361632] Add information about latest OM and agent in release.json

[viveksinghggits]

Summary

We have been getting some request from the customers where they wanted to know the combination of the container images that they require to run a specific version of operator and Mongo DB instance. As part of that work we are going to add a new file (release_info.json) as the assets in the GitHub release.
That file is going to have details about the latest released images. These images are going to be the images that MCK publishes as well as the latest OM and Agent version mappings. To enable that, as part of this PR we are adding a new field in the release.json that has the mapping between OM version and agent version of latest OM releases. This new field in the release.json is going to have the opsManaget to agent image version mapping for every major opsmanager version.
We are adding this information in the release.json so that it can easily be used later (in next PR), to create the release_info.json file.
This PR also updated the precommit hook so that when new version of OM is released, the newly added field of release.json would properly be updated with newly release OM/agent.

Proof of Work

Manual:

• Mimic new release of OM by adding a new version (8.0.17) to supportedImages.ops-manager.versions and respective entry in mongodb-agent.opsManagerMapping. Run make precommit and verify that the supportedImages.latestOpsManagerAgentMapping has been updated for major version 8 with updated versions.
• Mimic the new major version release of OM by adding new version (9.0.1) to supportedImages.ops-manager.versions and respective entry in mongodb-agent.opsManagerMapping. Run make precommit and verify that a new entry for major version 9 has been added to supportedImages.latestOpsManagerAgentMapping.

do you think we can replace the existing code here to use what you've implemented here?
