fix: some commands should ignore workspaces

[mshima]

Add condition so commands like npm prefix and npm whoami succeed inside a workspace.

let's swap conditions to avoid array traversing if workspaces are not enabled.

(workspacesEnabled || workspacesFilters.length > 0) && !['bin', 'cache', ...].includes(this.command)

Seems related to #4404, so maybe login/adduser cmd should be whitelisted here too.

@antongolub thanks for the review.
According to #4404 (comment), @fritzy is working on a fix.
This PR is kind of a workaround, and a proper fix probably is to rework https://github.com/npm/cli/blob/latest/lib/base-command.js predicting this kind of commands.
So I will wait a review from the team for now.

#4479 is a bit different in that we follow our static property pattern for commands (including tests to ensure each command has it), and we check for implicit vs. explicitly set workspaces.

Thanks for your submission!
