Bug 1871192 - [devtools] Add an exception from a11y_checks for a test purposefully clicking on a body element. r=ochameau,devtools-reviewers

This test is failing accessibility checks, because it sends a click on an empty `<body>` element in-context and this event is not expected to activate any control or interact with any other interacrive element, therefore this test click can be excluded from the a11y_checks.
