feat: added docker caching

[mguptahub]

Description

This pull request updates the Docker build and push GitHub Action to improve build caching and environment variable handling. The main changes add support for remote build cache storage, which should speed up subsequent builds, and ensure that image owner and name variables are available during the build process.

Enhancements to Docker build and push process:

• Added cache-from and cache-to options to both the standard and FIPS Docker image build steps, enabling the use of a remote build cache stored in the registry for faster builds.

Environment variable improvements:

• Set IMG_OWNER and IMG_NAME environment variables in both build steps to ensure the cache references are constructed correctly.
