I18N: Add context to Modern Image Formats section title

[alexclassroom]

Summary

The plugin name and the Media setting page section name are the same, "Modern Image Formats," so they are the same string, but they should be disambiguated by context.

Relevant technical choices

We don't translate plugin names, but even if the "Modern Image Formats" string in the Media setting page is the same as the plugin name, I think it should be a localizable setting page section name.
