Have meta-viewport map to SC 1.4.4 again

[WilcoFiers]

The meta-viewport rule used to map to SC 1.4.4, but is now considered a best practice. We changed this in axe-core v3.5. However in the meta viewport allows for zoom ACT rule, this is still considered a failure of SC 1.4.4. I think there's still a reasonable argument for doing so. Lots of people do not have the latest Iphone or Android device. Plus the default setting of Chrome and Firefox do prevent zoom. You can change it, but in the spirit of "without assistive technology", I'm not sure an "prevented by default" is actually sufficient.

Here's a recent write-up on the topic that was making the rounds: https://www.matuzo.at/blog/2022/please-stop-disabling-zoom/

This rule was approved by the ACT Task Force, and is scheduled for review by AGWG hopefully somewhere in September. If AGWG approves the rule for 1.4.4, we'll make the change in axe-core. We'll want to wait for that decision before making the change.

AGWG approved this change. We're updating axe-core.

Validated with the latest axe-core develop branch code base,
meta-viewport is failing in SC1.4.4 but not showing as best-practice for the test script:

<meta
  name="viewport"
  id="mvp"
  content="User-Scalable= no;
										 maximum-scale=2;"
/>
Footer

but for this test script it also fail for meta-viewport-large rule, which is having best-practice tag
