flink: add versions 1.17.1 and 1.18.0

[thomas-bouvier]

Hello all,

This is my first attempt at contributing to SDKMAN. Thank you for this great tool.

I'm trying to add Flink versions 1.17.1 and 1.18.0 but couldn't run ./gradlew clean run locally on my machine. It seems that no Docker container gets launched. Should that be the case?

I get the following:

I marked the PR as WIP.

Hi @thomas-bouvier,

indeed you need to start MongoDB as a Docker container first

docker run -d -p27017:27017 mongo:3.2

Thank you very much @helpermethod, I tested and the PR should be ok.
