CLOUDP-84352: generate OLM bundle during release process

[antonlisovenko]

Adds support for bundle generation during the release

I generated the release branch and tried to install it into the OLM. Everything was ok, though the deployment didn't succeed (which makes sense as we haven't released the new image yet)
I edited the deployment and change the image to mongodb/mongodb-atlas-kubernetes-operator-prerelease:CLOUDP-84352-olm-bundle-release-5a84c7e - after this it succeeded.
