deps: ember-wormhole@0.3.5

no issue
- we already have similar behaviour in the `liquid-wormhole` (a dependency of `liquid-tether) but this is useful as a distinction for non-animated elements. It's also a dependency of the ember mobiledoc editor (used to render component-cards inline much the same way as this is used to render image upload components inline) and so we wouldn't really gain anything in filesize by forcing the use of `liquid-wormhole` instead
