fix(e2e): fix setUserPreference to pass value as positional arg to occ user:setting

occ user:setting takes the value as a positional argument, not --value=VALUE.
The --value flag was silently ignored, so setUserPreference never actually set
the 'show' preference, causing the 'opens when a new major version was shipped'
test to always fail with the wizard landing on page 0 instead of the whats-new page.
