fix (build): Add (initial) missing CI test coverage for DevEnv 🫙

[vorburger]

Relates to #458

[vorburger]

As is, this currently fails on CI, due to:

#15 exporting layers 28.6s done
#15 writing image sha256:16f654ab58f4ad33c5973062c5e4a789b91dae2ffe0b55749bd5eec24d3b65aa done
#15 naming to docker.io/library/enola.dev-devenv done
#15 DONE 28.6s
the input device is not a TTY
Error: Process completed with exit code 1.

and I'm sure yet why... ideas welcome!

and I'm sure yet why... ideas welcome!

duh! That was just because the ./devenv.bash on CI cannot "enter the Terminal shell for a prompt" - only build it.

I've made it conditional now - that should hopefully do the trick...

Hm, but this will add 3m 41s to EVERY (no caching?!) build... I'm not entirely sure yet if I'm a huge fan of this.

No, wait a second, this adds >10' to every build! That's... really not great.

I would love to (have someone else?) further investigate 🔢 if there isn't a smart way to "cache Docker" (layers) on Actions, before merging this.

https://docs.docker.com/build/cache/backends/gha/ ? Seems simple enough...

But with hopefully we don't hit the 10 GB limit...
