Do not show image viewer for SVGs (#10435)

Absent some ability to toggle between viewing and editing a file, I
think it would be best to get a fix out quick for people to edit SVGs as
text files.

Release Notes:

- Fixed editing of SVG images by disabling it from the image viewer
([#10403](https://github.com/zed-industries/zed/issues/10403)).
