Docs: update release process

[am29d]

What were you searching in the docs?

We have updated the versioning and release processes and this needs to be reflected in the documentation. We have a release process diagram for that (see link).

Is this related to an existing documentation section?

https://docs.powertools.aws.dev/lambda/typescript/latest/maintainers/#release-process-visualized

How can we improve?

Update the visual representation of the release process according to the current state of `make-version` and `makre-release` workflows.

Got a suggestion in mind?
