finance/alkimia: switch to using WebEngine by default

Qt5Webkit will be removed at the end of the year.

See: commit e8e65e7

    www/qt5-webkit: mark for deletion

    Qt upstream switched to QtWebEngine quite a while ago, and the maintenance
    of QtWebKit was carried out by a separate person.
    Unfortunately, no release or updates have been pushed in the recent
    years.

    Note: there is a fork [1] of the used fork [2], that might be viable for people that
    really still need to rely on Qt5Webkit.
