Thank you for contributing!

We use apt-get instead of apt in these instructions so that the example commands can be used by users who want to script these steps (which in some cases can be as part of a Dockerfile). While apt is intended for "interactive" use, apt-get is still the recommended tool for scripting (as it has a stable API, whereas apt does not).

Some earlier discussions on this can be found in #8135, #10547, and probably some other ones.

I'm closing this PR because of the above, but thanks again for contributing, and feel free to continue the conversation.
