LPS-50152 Update alloy-editor to v0.2.2

Hey Nate, we're updating the alloyeditor to a new version.

We moved the skin to the editor in the hopes of removing completely all alloyeditor skin-related styles from portal. Unfortunately, some of the rules in portal beat us in specificity (mostly due to our `.aui` namespace), so we need to add some styles to override those.

Thanks!
