New Gatling and Scala versions are available

[dono-greeff]

With Scala 2.13 there is a lot of extra functionality that would be useful.

Also there are newer versions of Gatling too that are not included here.

I would be happy to contribute, however, I am by no means great with JAVA or Scala.

I assume it is simply updating the openJDK image and gatling versions.

Also I do not have permissions to contribute anyway.

@denvazh gentle bump :)

@denvazh There's a forked library which has the latest version (3.5). Any chance you would be able to update your repo as well?
