If you look at the ENTRYPOINT docs, one form is already a shell form,
so it's running a shell for you, apparently.

More imporant than whether bash is used, is that if you don't have
your own init-style process inside the container, you may wish to use
the --init option on the docker-run command line, depending on your
use case, or if your entry point command spawns child process or not.
I don't think bash will suffice for that.
