This reverts commit 12ae6e4.
The intent of the previous code was "latest 2.x", meaning 2.2 currently. In reality, "wcag2aa" means "2.0" specifically. Ref: https://github.com/dequelabs/axe-core/blob/master/doc/API.md#axe-core-tags

馃洜 Summary of changes
Enhances existing accessibility checks to verify that no duplicate IDs exist.
Related WCAG Failure: F77: Failure of Success Criterion 4.1.1 due to duplicate values of type ID
Previous discussion: #10289 (comment)
Ideally this would be something our existing Axe-based testing tools could identify (Axe even has an article for a related rule), but I could not cause an issue to be flagged in my testing with either the Ruby-based Axe tool nor the Chrome browser extension.
馃摐 Testing Plan
Verify that build with commit including demonstrated failure fails (12ae6e4), and passes without.
(TBD if there's any existing issues that will need to be fixed)
