Create a Space - Create Team Space Modal : aria-hidden="true" is used incorrectly

Issue Summary

For the  Create Space modal, aria-hidden="true" is used on informative content making it inaccessible to assistive technology.

Steps to Reproduce

1. Navigate to the  Confluence header section.
2. Navigate to the "Spaces" button present in the header region and activate it.
3. Navigate to the "Create a space" link and activate it. Observe that create a space modal dialog appears on the page.

Actual Results

The "aria-hidden" attribute is provided to the "Create Space", which becomes available on selecting the Create Space option. As a result, screen reader users cannot access the modal effectively.

Expected Results

Remove aria-hidden=”true” from the <div> element in the page source for the modal.

The aria-hidden="true" attribute is used to hide the content from assistive technology users. Although it is a best practice to use the aria-hidden="true" attribute to hide irrelevant content for screen reader users, it can pose issues for screen reader users if it is not used correctly. 
Additionally, ensure the focus does not move out of the modal in the background content unless the modal is closed.
