CalendarMonth missing OUIA Support

[mshriver]

Describe the enhancement or change
The CalendarMonth component does not support OUIA props, preventing test automation tools from leveraging this support with these components.

This request is related to the Satellite and Insights Red Hat product teams.

OUIA support is already well defined and included for many components.
