Problem/Motivation
The default entity view display for media lacks an image style in the standard and demo umami profiles.
core/profiles/demo_umami/config/install/core.entity_view_display.media.image.default.yml
core/profiles/standard/config/optional/core.entity_view_display.media.image.default.yml
If a site builder doesn't update this, it can lead to very large images being served using the default configuration.
See #3066802-2: Ensure that embedded media displays sanely by default for an initial description of the issue by Wim Leers in the context of media embeds. Then in #3066802-118: Ensure that embedded media displays sanely by default, Effulgentsia pointed out this is not just an issue for embeds, and it should be looked into outside of that issue.
Proposed resolution
As a sensible default, add the 'large' image style on the standard profile, and the '3:2 Image' responsive image style for the Demo Umami profile. The label should be visually hidden and image_link (link to file) should be disabled by default.
Remaining tasks
TBD
User interface changes
No need for the user to configure image style when first installing standard and demo umami for the default media image entity view display.
API changes
none
Data model changes
