Complete Sprint Modal : aria-hidden="true" is used incorrectly for the complete sprint modal.

Issue Summary

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

Steps to Reproduce

1. In the Jira header, navigate to the Projects link and activate any of the projects.
2. In the available sidebar of the Jira, select the "Active sprints" link.
3. In the available main content area, navigate to the Complete sprint button and activate it.
4. For the available Complete sprint modal, inspect the board and try to interact with it.

Actual Results

The "aria-hidden" attribute is provided to the Create board macro, which becomes available on activating the Create board button. 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.
