Describe the Bug

Problem: When using wrangler pubsub <subcommand>, the .epilogue() with a beta warning does not show. Instead, it does show when you use --help on second or third -level subcommands, and is invoked multiple times (once for each command in the group).

Expectation: The .epilogue(pubSubBetaWarning) is invoked once on every command under the pubsub command group

It's likely I've used .epilogue() incorrectly.

e.g.

Invoked on top-level --help multiple times
