Incompatible with click==8.0.1

[DuneRaccoon]

I'm not sure if this issue has been raised, but line 101 in cli.py isn't compatible with the current version of click:

@click.option( '--extra-path', default='.', multiple=True, help='Append specified directories to sys.path')

default must be a list if multiple is True is the error raised.

#383 #385 trying to fix this very thing, awaiting code review and merge.

For anyone waiting on the pull request to get merged, you can do pip install click==7.1.2 after installing rq-dashboard to avoid broken deployments in the meanwhile.
