As reported by @mpsijm, the feature for the version check (/versions) is great but if you use new languages you can see that we don't know the version but not how to change it. It would require knowledge of the code to know that this should be done on the /lanugages interface.
The goal you want to achieve
Add the button to edit the version check somewhere to directly fix this.
Other info?
A follow-up can be to also have a specific job to get the version, I think that's overkill as this doesnt happen often and would be a branch we almost never hit as it requires usage of this feature (not well spread) and using an barely used but known language.
Add the edit button on the versions page
