Ability to give megalinter container an arbitrary name

[dmitri-trofimov]

Is your feature request related to a problem? Please describe.
As a megalinter user on Windows I'd like to have an ability to run megalinter and supply a name to the Docker container it runs in so that I have less random container names in my Docker Desktop application.

Describe the solution you'd like
By looking at the megalinter runner code, it seems quite easy to add an option like --containername and pass it to Docker docker ... --name <containername>. I can try and create a PR for that.

Describe alternatives you've considered
I don't know of any alternatives.

Additional context
When a Docker container is run, it is given a random name (redesigned-train or quantum-fish...). Although I am not sure if this happens on Linux machines, it definetly happen on Windows in Docker Desktop. It also saves the containers, and after a few runs you get a list of many random looking containers in the list. I'd much rather prefer havin only one line corresponding to the megalinter.

Yes, this also happened on Linux, so thank you for the fix!
