environment variable from the image stream name instead of using a
hardcoded value
Derive the value of the JBOSS_IMAGE_VERSION information environment
variable from the "project_versionDoc" attribute instead of using
a hardcoded value, since the current "project_versionDoc" value matches
the "7.4" value currently present in the images
Drop the "JBOSS_IMAGE_RELEASE" and "STI_BUILDER" information environment
variables, since they aren't present in the latest version(s) of the
OpenJDK / OpenJ9 images any more
Add raw GitHub locations of the OpenJDK and OpenJ9 RH-SSO 7.4 templates
to be ignored by the tests (currently there are just RH-SSO 7.3 and
RH-SSO CD versions of these)
