Switch to JDK 18 + newer command-line sdkmanager?

[karlhorky]

The newer sdkmanager from the Command-Line Tools package now supports JDK versions newer than 8: https://stackoverflow.com/a/65782803/1268612

Would you be open to switching to JDK 18 and the new command-line sdkmanager?

There's an example here that may be helpful in getting this set up:

@karlhorky For sure!

It has been a while I have used it myself but I am more than open to accept any PRs. When I have little bit more time, will try to do it myself too.
