This change deletes the potrace rules from imagemagick. Otherwise it tries to use potrace, which is not installed and would create ugly monochrome slides. Without this change, d8350f813c/bbb-common-web/src/main/java/org/bigbluebutton/presentation/imp/SvgImageCreatorImp.java (L223) fails in the docker version of BBB. The users see this effect as blank slides. This path is triggered by type 3 fonts in the page.
Background: bbb-web tries to avoid pdftocairo for pages with type 3 fonts, see https://gitlab.freedesktop.org/poppler/poppler/-/issues/268
And imagemagick changed its behaviour around version 7.0.8-65, see https://legacy.imagemagick.org/discourse-server/viewtopic.php?t=36777
