Resolve "Error when using backup-utility with GitLab 17.5.4"

What does this MR do?

We pin gsutil but not pyOpenSSL which is a direct dependency that gets installed when we pip3 install gsutil.

The latest version 24.3.0 introduces 2 breaking changes which break gsutil.

The pyOpenSSL 24.3.0 release notes say:

Removed the deprecated OpenSSL.crypto.sign and OpenSSL.crypto.verify. cryptography.hazmat.primitives.asymmetric’s signature APIs should be used instead.

Run gsutil -m cp -r gs://<bucket-path> / to copy a remote object to local storage.

The gsutil will raise the module 'OpenSSL.crypto' has no attribute 'sign' error.

Proposal

• Pin pyOpenSSL to 24.2.1.
• Use ci_files/variables.yml for version tracking.

Possible follow-ups

Create a Renovate config pinning pyOpenSSL to 24.2.1.
