As reported by @Bennylin at https://wikitech.wikimedia.org/wiki/Help_talk:Toolforge/Kubernetes#Errors:
$ webservice --backend=kubernetes php5.6 shell type must be one of: buildservice * golang1.11 * jdk17 * node16 * node18 * perl5.32 * php7.4 * python3.11 * python3.9 * ruby2.1 * ruby2.7 * ruby3.1 * tcl8.6
Not printing the deprecated version strings is fine, but the container should still be usable. We haven't done a round of warnings about it's removal. (We should! We just haven't yet.)
