fix: Docker deploy script exit on error

[TubSticks]

Closes #6287

📑 Description

The Docker deployment script of Keep does not exit or act when one of the checks fails. For example: it checks whether the folder "state" exists and whether "curl" is installed, but it doesn't act when the exit code is greater than 0. Setting the -e flag in the script solves this and makes sure the script stops when the exit code is 1 or higher.
