Enhancement to remove-user sub command

[mdrovdahl]

Some sites may have disabled the Jetpack JSON API module, meaning that we can't search their users for purposes of user removal:

markd@MBP14 team51-cli % BEARER='[REDACTED_TOKEN]'; curl -sH 'Accept: application/json' -H 'Authorization: Bearer '$BEARER 'https://public-api.wordpress.com/rest/v1.1/sites/[REDACTED_BLOG_ID]/users/?search=[REDACTED_EMAIL_ADDRESS]&search_columns=user_email&fields=ID,email,site_ID,URL' 2>/dev/null | jq .
{
  "error": "unauthorized",
  "message": "API calls to this blog have been disabled."
} 

In an ideal world, when we receive this response, we would alert the CLI user which site(s) have been skipped so that they can manually process removals.

Just noting that the list of sites that return that error is rather large ...
