flow dependencies install --skip-update-prompts does not work

[turbolent]

Problem

flow dependencies install --help says:

--skip-update-prompts Skip prompting to update existing dependencies

However, even when passing the option, I'm still being prompted if I want to update.

Steps to Reproduce

1. Run flow dependencies install --skip-update-prompts
2. Get prompted to update outdated dependency

Acceptance Criteria

Option works as expected, or remove if unimplemented
