fix: running npm commands in npm exec

[darcyclarke]

Current Behavior

• npm exec -ws -c 'npm whoami' fails because workspaces is passed into the subprocess as an environment var
• npm exec -w foo -c 'npm whoami' fails because workspace is passed into the subprocess as an environment var

Expected Behavior

• npm exec should not pass on workspace or workspaces config into the env

Exit Criteria

• bug should be fixed
• documentation should exist for npm exec that explicitly outlines the absence of those envs from the subprocess
• documentation should be updated to use --ws wherever -ws currently is marked (ex. examples)

issue seems to have been fixed in between the original post and now, just tested with npm@7.10.0 and it works as intended:

$ npm exec -ws -c 'npm whoami'
ruyadorno
ruyadorno
ruyadorno
ruyadorno
ruyadorno

$ npm exec -ws -c 'npm ls'
