chore: add devcontainer with java17

[mikaello]

Thanks for a very nice utility (+1 to #1)!

Since the heroku-site is down, it may be nice to give users a devcontainers file with correct java version, that way they are only a click away from having a dev environment with Java 17 installed and ready to install with Maven and run the jar-files.

I think package it to Linux package manager is more convenient.

@ris58h Can you publish a version tag? It can help packager to package this program 😄

I don't fully agree. By solely supporting a Linux package manager, I would need to install the package on my computer to run the software. However, with the approach proposed in this merge request, users can perform all tasks in the browser without the necessity of installing anything on their computers.

I believe giving the users the option to choose for themselves would be best. :-)

Oh, I see. You only need exported APK, not this program. In my situation, I must try many times to find a propitiate layout: swap two keys, try for a long time, feel not good and reexport a new APK with swapping other keys and try again. So I hope it can installed in my machine for convenience.
