feat: prompt for login any time a user omits API key

🚥 Fix RM-5540

🧰 Changes

This updates all of our commands so that when they're run locally and the user omits the --key parameter (and they're running the command from a non-CI environment), we now prompt the user to log in, rather than just erroring out. Most of this diff is just a super tiny refactor to all commands and then refactoring a bunch of tests to account for this change.

Here's what it looks like when a user omits the --key flag and attempts to run a command that requires authentication:

Also did a tiny bit of test housekeeping:

• Added some nock cleanup logic to our docs:edit tests to be consistent with every other test suite 🧹
• Stricter login command nocks 💪🏽

🧬 QA & Testing

Our testbed covers this, but if you want to test this out, you can check out this branch and run this flow of commands:

# Set up rdme
npm ci && npm run build
# Just in case...
bin/rdme logout
# Now try running an authenticated command and follow the prompts
bin/rdme openapi

well shit, you made this look easy. we should've had these commands do this this whole time.
