Update OpenJDK to 11.0.14.1

See #2315. This only updates  the x86/amd64 version, and does not bump the arm64 version, since it is [not yet available](https://hub.docker.com/r/bellsoft/liberica-openjdk-alpine/tags). arm64 is not urgent (to my knowledge) since it is only used for local Mac M1 development.

 # Docker's BuildKit skips unused stages so the image for the platform that isn't used will not be built.
