docs: Update npm-doctor.md

[siemhesda]

Changing description under npm doctor command to make it clearer

[wraithgar]

You're gonna want to run npm snap to update the docs snapshots I believe

[wraithgar]

Apparently not!

[wraithgar]

Oh now I remember. You need to change the description attribute in lib/commands/doctor.js and then run npm run build -w docs. You'll also want to run npm run snap to update the test snapshots for the help output for the cli itself.

Hi @wraithgar,
Check it out once more?

[wraithgar]

You still need to commit the results of npm run snap

[siemhesda]

Hi @wraithgar why are we tracking node_modules in the .gitignore line 30

[wraithgar]

npm "vendors" its node_modules, but only production dependencies. The .gitignore reflects this and we have automated tooling to keep it up to date.

[siemhesda]

I did a commit for the command

[wraithgar]

Not sure why your changes aren't propagating when you update snapshots. Were there other files that didn't get committed?

[siemhesda]

I also made a commit for npm run build -w doc that I had had not run before. How does it look now?

[wraithgar]

Yay looks like we got there!
