Feature/pdp fetch priority

[gabridevs]

What problem is this solving?

This change improves page performance by ensuring the main product image is prioritized during loading. By setting the fetchpriority: 'high' for the first product image, we ensure that the most important image (usually the first one) is loaded first, enhancing user experience, especially for pages with multiple images.

How to test it?

You can test this change by visiting the following workspace where the branch is linked. Check the loading behavior of the first product image, ensuring it is loaded before others when opening a product page.

I would also request that you:

• fix conflicts in CHANGELOG.md
• provide an up to date and working workspace

Hi @vmourac-vtex i have update workspace and CHANGELOG.md

@gabridevs it seems you missed some some of the requests in earlier messages. We could also improve on the way you handled the CHANGELOG.md fix. I'll summarize what still needs to be done here:

• This PR should only contain the changes related to this task. Currently it is mixed with #1120. Please recreate/interactively rebase, etc, in order to only include commits and changes related to the task proposed in the PR
• Fix conflicts on CHANGELOG.md - You fixed the conflicts by removing your changes in this file. The root issue was that your branch diverged from this repo master branch. Reconcile the branches and then add to CHANGELOG.md what you added/removed/changed in this PR
