Avoid SVG conversion for pulled SVG from Cloudinary if SVG support is enabled

[gabrielcld2]

When we pull an SVG from Cloudinary, if SVG support is enabled we should expect it to be disabled as an SVG file.

However, it is currently displaying as a PNG.

Approach

• If the setting is supported, disable SVG conversion using the cloudinary_convert_media_types filter

QA notes

• Go to Cloudinary Image Settings page
  • Make sure SVG Support toggle is enabled
• Create a new post/page
  • Add an image block
    • Import an SVG from Cloudinary (if none are present in your account, import one using Cloudinary DAM)
  • Make sure the SVG is displayed as an SVG on the editor
  • Publish and view the post
    • Check that it displays as an SVG on the frontend too and that it has expected SVG transformations (e.g. f_svg,q_auto/fl_sanitize)
• Go back to Cloudinary Image Settings page
  • Toggle OFF the SVG Support setting
• Follow the same previous step to add a new post with an uploaded SVG
  • It should be converted to a PNG
