[IMP] theme_anelusia: replace banner with text_cover

The new text_cover snippet introduced in commit [1] reproduces the same
result as the Anelusia banner. It makes more sense to use now this new
snippet and get rid of the banner customizations.

This commit removes banner customizations in favor of text_cover
snippet.

As the text_cover snippet is not yet managed in the svg preview, this
snippet uses the banner image.
