- install cmake 3.18.1 for android - cmake version didn't change during the upgrade but probably by default a different version is used now
- use java 17
- don't set PATH variable - it was breaking ci on github and causing ci to use outdated system ruby and bundler, I don't know why it was introduced (it was just modified here: https://phab.comm.dev/D6785 to fix buildkite build) but after removing it it works on github, buildkite and in nix
Depends on D15167
