Following discussion #5418 noting consistency updates for the generated published documentation pages,

  $ sudo hasura completion bash --file=/etc/bash.completion.d/hasura

CLI help text propagated to also show an inconsistent CLI docs page.

Should update sudo hasura completion bash --file=/etc/bash.completion.d/hasura to `sudo hasura completion bash --file=/etc/bash_completion.d/hasura

This was previously updated in another instance; however, there are additional occurrences that should be updated to maintain consistency.
