Original change's description:
> Reland Update axe-core to v3.3.2
> 
> This change updates the version of axe-core to the latest released
> version. As part of picking up the latest version, the following
> additional changes were made:
> 
> 1) axe-core removed the 'href-no-hash' rule, so that been removed
>    from the test list.
> 
> 2) Several 'link-in-text-block' tests started failing with
>    axe-core v3.0.2 (and later). These tests do pass in v3.0.1, but
>    are disabled as part of this change.
>      - CrManagementA11yTest.SimpleTest_link_in_text_block
>      - CrManagementA11yTestWithExtension.
>                                 ExtensionSection_link_in_text_block
>      - CrostiniAccessibilityTest.CROSTINI_link_in_text_block
>      - CrExtensionsA11yTest.NoExtensions_link_in_text_block
>      - MultideviceA11yTest.MULTIDEVICE_link_in_text_block
>      - MultideviceFeaturesA11yTest.
>               MULTIDEVICE_FEATURES_ACCESSIBILITY_link_in_text_block
> 
> 3) One 'heading-order' test started failing in v3.0.0 (and later).
>    This tests does pass in V2.4.2, but is disabled as part of this
>    change.
>      - CrExtensionsA11yTestWithMultipleExensions.
>                                        WithExtensions_heading_order
> 
> 4) Several DevTools a11y tests were failing. This change either
>    updates the baseline or excludes the rule depending upon the
>    test/rule itself.
