test-infra Refactor and rewrite Python scripts in releng/ in Go

What should be cleaned up or changed:

We have a bunch of Python scripts in releng/ directory. These scripts are used to handle creating release branch jobs. These scripts also:

fetch values such as latest Kubernetes and Go version
handle updating auto-generated files
handle removing jobs for EOL release branches
wrap config-rotator and config-forker written in Go

These Python scripts have several problems:

We need to run them in a Docker container to ensure correct Python version and environment. There are some issues and challenges doing that on Mac M1 and M2
Kubernetes is a Go project and many of us are more experienced in Go. Having these scripts in Go would make it easier to run and test those scripts, but also refactor and debug when needed

That said, I think we should consider rewriting these scripts in Go. Additionally, we should consider wrapping everything (config-rotator, config-forker, and existing Python scripts) in a single binary.

Provide any links for context:

See #29387 for more details

Update: some of the Python scripts might be removed as we consider replacing them with already existing fork-per-release mechanism.

@Rajalakshmi-Girish is working on getting rid of some of these Python scripts by utilizing forker and rotator. /unassign @xmudrii @sbdtu5498 /assign @Rajalakshmi-Girish
