Fix the 'Fallback to JQueryUI Compat activated' for Magento version 2.3.3 and above

[toan-tam]

Issue:

• After installing the module on a Magento version 2.3.3 (or above), the following warning stated on the console:

Fallback to JQueryUI Compat activated. Your store is missing a dependency for a jQueryUI widget. Identifying and addressing the dependency will drastically improve the performance of your site.

The reason the issue occurs is that we inject the 'jquery/ui' as a dependency to our mixin and from Magento 2.3.3, jquery UI is restructured and causes the issue.

Proposal solution:

• Remove 'jquery/ui' as a dependency on mixin Yireo_Webp2/js/swatch-renderer as we don't need to inject 'jquery/ui' when creating a mixin.

Hi @jissereitsma, Can you help review this PR?

[jissereitsma]

Thanks, it is a small change but very important indeed - as you point out. The involved JS file originates from a third party PR and I can see that in the past some jQuery UI logic was needed. But currently, there is not, which makes your PR completely needed. Thanks again! Merging right away.
