chore: Generate global constant and sec scan config for docker images

[hisarbalik]

Description

Any docker image update requires updating several files, such as source code and yaml files. To make the module release and image bumps more straightforward, the docker images are maintained from a single source .env file. All other source code and configuration files, like sec-scanner-config.yaml, are generated from the .env file.

Changes proposed in this pull request (what was done and why):

• Add go code generator to generate docker image constants from .env file
• Generate sec-scanner-config.yaml from .env file
• Update release docs with new steps
• Add go code and sec-scanner-config.yaml generation to the make generate target
• Load docker images from .env file for benchmark tests
• Add code generation to the check-clean target to ensure source code and configuration files are up-to-date
