I believe there is a way to have dependabot increment the environment variable based on the latest image tag available.

Let's pursue that option if possible. That way, we wouldn't have to make too changes to the existing scripts

If you have a way to do this, then that would be preferred. For this case, specifying the version and the dist directly is redundant since we only produce a single image flavour in any case. The priority here is ensuring that the base images are up to date and not maintaining the existing scripts -- unless the functionality is actually used.

Thanks @cdesiniotis. With @tariq1890's comments noted, I still think this is a worthwhile change as it removes a manual and specifically mechanical step from what is required to keep our images up to date.

If we do have a way to so this in the context of the existing logic, I'd be happy to consider that too. For now, this looks good though.

Looks like what I said possible in renovate bot. More details here: https://docs.renovatebot.com/modules/manager/regex/

Not sure if dependabot has a similar feature. Definitely worth investigating.

FYI - My comments aren't blocking
