If we uploaded small image that is already optimized then delete webp version, optimize btn is displayed instead of just change delete link to generate link

To Reproduce
Steps to reproduce the behavior:

1. WebP is enabled on trunk or on AVIF branch, the AVIF is off
2. upload small image like the one attached
3. check media library
4. click delete webp image or delete Next-Gen link => optimize btn displayed

Expected behavior
When click delete webp or next-gen, switch the link to generate webp or next-gen (as we didn't delete optimized images)

• on trunk, delete webp isnot displayed for large image

Acceptance Criteria (for WP Media team use only)
Clear instructions for developers, to be added before the grooming

• When click on delete link, generate link displayed after deletion
• When click on generate link, delete link is displayed after generation
• This applies to big/small image
• link displayed in media library and image edit

Start by reproducing the behavior in the WordPress media library and image edit views with WebP enabled and AVIF disabled, using a small already-optimized image. Check the delete and generate link states for both small and large images. Done means deletion shows the generate link and generation shows the delete link in both views.
