Replace apt with apt-get to Avoid Unstable CLI Interface Warning in Docker Build

[foxytanuki]

We're receiving a warning about apt's unstable CLI interface in our Docker build. I recommend switching to apt-get to resolve this.

Here is an excerpt from our build log showing the warning:

Step 5/13 : RUN apt update && apt install -y curl
 ---> Running in f45ef5370a50

WARNING: apt does not have a stable CLI interface. Use with caution in scripts.

Using apt-get in place of apt is recommended for script usage as it provides a stable CLI interface.
