Dear maintainer, below is a concise technical summary of the changes proposed in this PR:

Introduce an environment variable CKV_SKIP_PACKAGE_UPDATE_CHECK to allow users to skip package update checks in checkov. Modify the check_for_update function in version_manager.py to accept a new parameter skip_check and return early if the check is skipped. Update banner.py to utilize this new parameter when checking for updates. Add the new environment variable to env_vars_config.py for configuration.

Hi @isality , and thanks for the contribution! Out of curiosity, what would be the reason for that behaviour?

@Saarett hello!

I use checkov in the cloud where there is no Internet access. If I understood you correctly.
