Subject: [PATCH 2/2] [patch] `no-redundandant-roles`: allow `<img src="*.svg"
 role="img" />`

Setting role="img" is a valid use case to work around a Safari bug for better accessibility when the source image is an SVG file.
This improvement does not account for variables in the `src` attribute but adds a valid exception for when we can parse the string.
Fixes #936
