testcontainers-scala-mockserver fails to download default version of jamesdbloom/mockserver since v0.38.6

[rogern]

After version 0.38.5 it seems that behaviour has changed in how versions should be specified and mockserver hasn't been updated.

It fails on:
com.github.dockerjava.api.exception.NotFoundException: Status 404: {"message":"manifest for jamesdbloom/mockserver:mockserver-mockserver-5.5.4 not found: manifest unknown: manifest unknown"}
because the name is duplicated. It should be:
jamesdbloom/mockserver:mockserver-5.5.4

I've tried the latest non alpha too: 0.40.2
