[azatsarynnyy]

The HappyPath tests are failed due to the known problem.
See https://www.eclipse.org/lists/che-dev/msg04194.html
I'm going to merge the PR as the proposed changes are related to build, release and docs. But not related to Che-Theia end-user functionality.
We need to merge these changes ASAP to finish switching the default branch from master to main. eclipse-che/che#20000

The built image can be tested with the following Devfile:

apiVersion: 1.0.0
metadata:
  name: main
attributes:
  persistVolumes: 'false'
components:
  - memoryLimit: 512Mi
