Description of changes:

Add Corretto 19 images

Basically followed https://github.com/corretto/corretto-docker/commit/3466cc5e4f6c086e321d97658cbaa64efe678c08 and cross referenced with latest Dockerfiles.

Did some sanity checks:

20220919-12:34:44
@laptop:/Volumes/workplace/corretto/corretto-docker/19$ grep -rc "\-19"
./jdk/alpine/3.14/Dockerfile:1
./jdk/alpine/3.13/Dockerfile:1
./jdk/alpine/3.15/Dockerfile:1
./jdk/debian/Dockerfile:2
./jdk/al2/Dockerfile:3
./slim/alpine/Dockerfile:4
./slim/debian/Dockerfile:5
./slim/al2/Dockerfile:32

@laptop:/Volumes/workplace/corretto/corretto-docker/19$ grep -rc "19.0.0.36"
./jdk/alpine/3.14/Dockerfile:1
./jdk/alpine/3.13/Dockerfile:1
./jdk/alpine/3.15/Dockerfile:1
./jdk/debian/Dockerfile:1
./jdk/al2/Dockerfile:1
./slim/alpine/Dockerfile:1
./slim/debian/Dockerfile:1
./slim/al2/Dockerfile:1

# Compare to 18

@laptop:/Volumes/workplace/corretto/corretto-docker/18$ grep -rc "\-18"
./jdk/alpine/3.14/Dockerfile:1
./jdk/alpine/3.13/Dockerfile:1
./jdk/alpine/3.15/Dockerfile:1
./jdk/debian/Dockerfile:2
./jdk/al2/Dockerfile:3
./slim/alpine/Dockerfile:4
./slim/debian/Dockerfile:5
./slim/al2/Dockerfile:32

@laptop:/Volumes/workplace/corretto/corretto-docker/18$ grep -rc "18.0.2.9"
./jdk/alpine/3.14/Dockerfile:1
./jdk/alpine/3.13/Dockerfile:1
./jdk/alpine/3.15/Dockerfile:1
./jdk/debian/Dockerfile:1
./jdk/al2/Dockerfile:1
./slim/alpine/Dockerfile:0 # https://github.com/corretto/corretto-docker/blob/main/18/slim/alpine/Dockerfile#L3 has wrong version. Will update in a separate PR
./slim/debian/Dockerfile:1
./slim/al2/Dockerfile:1

Note: https://github.com/corretto/corretto-docker/blob/main/18/slim/alpine/Dockerfile#L3 seems to have wrong version so 18/slim/alpine/Dockerfile has different grep output from 19/slim/alpine/Dockerfile. Will update for 18 in a separate PR. 18 will be removed soon. Slim docker images are not vended anywhere.
