[WebUI Test] Disable AX_ARIA_08 in accessibility audit.

[WebUI Test] Disable AX_ARIA_08 in accessibility audit.

Recently there are lots of accessibility failures for AX_ARIA_08. Rather
than playing whack-a-mole by disabling individual tests, we should disable
the test case until the root cause is found and fixed.

BUG=657514
