Do not deprecate GenericContainer(String dockerImageName)

[dturanski]

I don't understand why this would be deprecated. DockerImageName seems to provide more value to the framework than the user. In most cases, it's just an unnecessary step for the user.

Hey @dturanski,

It was left deprecated by a mistake and is already fixed in #3102. Sorry for that!

I am using 1.17.1 and it still says deprecated.
