Don't use NuxtImage for SVG

[nicolaskempf57]

Most of our 504 from last Sunday related to _ipx are with SVG.
I think we can use plain img for them and if we want to optimize them, we can pass them to svgo in a PR and not at runtime.

cat 504.log | grep .svg | wc -l
6740

cat 504.log | grep .svg | grep -v logo_text | wc -l
2962

cat 504.log | grep _ipx | grep -v .svg | wc -l
