[Bug]: steamcmd sometimes without remotebuild causing an alert to be sent

### User story

As a serveradmin i want that no Alerts are sent if there is no remote build

### Game

gmodserver

### Linux distro

Ubuntu 22.04

### Command

command: update

### Further information

Sometimes steamcmd doesn't get a remotebuild version. So far lgsm is validating the gamefiles which isn't a problem. Cause the localbuild is avaiable and there isn't a remotebuild, lgsm is sending an alert for an "update success".
The gameversion didn't change, so it shouldn't send an alert. I guess the alert comes just if the two values are not the same.

I really don't know what happend to steamcmd with the remotebuild. The messages started 2 days ago.
The screenshot is after the update, as you can see, the version didn't change.
