Updating with postgres or redis will fail

[nomisge]

Hello,

Running an update for e.g. postgres the resulting compose file will have image: nexcloud: ... instead of image: postgres: ...

I already reported the issue via mail. But since nothing happened, and since I found a possible solution, I'll post it here in the spirit of open source (no time to run tests and create a pull request).

The following line is wrong:

nextcloud-cli/nextcloud-cli.py

Line 789 in 2989f19

compose_data["services"][service]["image"] = f"nextcloud:{new_version}"

It is supposed to be:
compose_data["services"][service]["image"] = f"{service}:{new_version}"

Hope that info is useful.
