Vector images broken with plugin active

[DanMan]

This is a follow up to #59, so all the preconditions are the same.

We are using a SVG image for the logo. Right now the plugin tries to convert those images, too, which fails and leads to a broken image in the browser. They don't seem to try the SVG among the sources, if the WebP image fails to load.

The plugin should just leave vector images alone. It doesn't make sense to try to convert them anyway.

Can you test the attachment commit?

Yup, logo shows up again. Thanks.

It lists the same SVG in 3 <source> elements, which is silly, but that might just be Shopware itself doing that.
