Convert Gradle config parameters jib.container.environment to use lazy evaluation

[FrogDevelopper]

Just like the like the jib.container.labels , the jib.container.environment property should use lazy evaluation.
This will avoid having a mix of lazy/direct parameters set in the configuration

Hi @FrogDevelopper, thanks for bringing this up. We are welcoming contributions to jib and we will gladly review any incoming PRs.

We have had similar situations with other fields (e.g. #3094 and #3709) - they may be a good start point.

Thanks!
