Enhancing Terraform Feature Stability

[Bulat Khusnimardanov (bulat-khusnimardanov)]

Description:
This pull request aims to enhance the stability of the Terraform feature by addressing a limitation in the ensure_cosign function. The function currently relies on the GitHub API for retrieving information, but this API has usage limitations, allowing only 60 calls per hour for non-authorized users (as documented here).

Problem:
The existing implementation poses challenges, especially within corporate networks where multiple users often share the same external IP address. This setup can quickly exhaust the rate limit, disrupting the reliability of the feature.

Solution:
This pull request introduces a solution to address the rate-limiting issue. A fallback method has been implemented to retrieve the latest cosign version number.
This pull request presents a solution to mitigate the rate-limiting issue. Instead of implementing a separate fallback mechanism, we've leveraged the existing function, find_version_from_git_tags, to retrieve the latest cosign version. This approach, as suggested by Samruddhi Khandale (@samruddhikhandale), streamlines the codebase and effectively overcomes the rate-limiting constraint.

Changes Made:
- Implemented a fallback mechanism to retrieve the latest cosign version number.

• Replaced the direct GitHub API call by the existing find_version_from_git_tags function.

Thank you so much for taking the time to contribute the PR.
I agree that we should avoid using Git APIs due to the limits 👍

Left one comment on the approach!
