Previously the mapping was just $this->installLatestMajor ? 'yes' : '', so a stored value of 'no' was truthy and would have been turned into INSTALL_LATEST_MAJOR=yes in the Nextcloud container — the opposite of what the user intended. Now both ''

and 'no' result in an empty env value, which the entrypoint's [ "$INSTALL_LATEST_MAJOR" = yes ] check treats as disabled, while any other value (e.g. the '34' set by the start button or upgrade button) still maps to yes.
