Spike - Investigate options for updating a11y props being required or not

Describe the enhancement or change
Spike for a discussion to have regarding https://github.com/patternfly/patternfly-react/issues/5397

Basically we need to decide whether:

• we want to update certain a11y props to either be required (if currently optional) or make them optional (if currently required)

• we want to add console warnings when an optional a11y prop is not passed in, but ideally should be (e.g. if an element doesn't have a visible text label, typically we should want an aria-label added somewhere)

• leave things as-is - props will remain optional or required as they already are

• some combination of all of the above

• some props should have an (updated?) default value

Is this request originating from a Red Hat product team? If so, which ones and is there any sort of deadline for this enhancement?

Any other information?

Jira Issue: PF-108

Start by reading the linked PatternFly issue #5397 and reviewing the current required and optional accessibility props across the affected components. Compare the options described here, including warnings and defaults. Done means the alternatives, affected props, and a recommended direction are documented for discussion.
