fix: make eager prop work again for Image and skip lazy load if prop isEager

[Giov7]

This PR fixes a problem on the Image block which doesn't allow eager loading. That's happening because of vtex render runtime non-handling the image prop correctly.

How to test it? *

I tested this behaviour here: https://www.whirlpool.it/?workspace=testkg65

Pull request overview

This PR ensures that images explicitly marked for eager loading are not overridden by the render-runtime’s lazy-loading behavior, so the Image block’s eager-loading configuration works as intended.

Changes:

• Introduces an isEager check in MaybeLazyImage based on imageProps.loading === 'eager'.
• Skips applying both native lazy-loading (loading="lazy") and the lazysizes logic when the image is eager, while preserving the existing preload (data-vtex-preload) behavior.

Hi @Giov7 thanks for submitting your PR!

Your change makes sense and seems in line with loading behavior in components like ProductImage, InfoCard, etc.

@iago1501 @vsseixaso what do you think?

Regardless, I would ask you to:

• Modify the CHANGELOG file with your proposed change
• Add tests to validate your changes

Hi @vmourac-vtex, I updated the CHANGELOG as requested. The tests done can be seen in https://www.whirlpool.it/?workspace=testkg65 where I linked my fork and noticed the behavior of Image component was correct when choosing between lazy and eager loading.
