Please release new version

[johnjaylward]

After releasing a new version of groovy-ssh : int128/groovy-ssh#400 can you also update the gradle plugin to use the new version and perform a new release?

@int128 Thank you so much for taking care of this project despite being so busy. Glad to see Groovy SSH moved into this repo for easier maintenance. ❤.
