chore(dialog): use isOpen type for open control

[marissahuysentruyt]

Description

This PR correctly implements the isOpen shared type on the dialog pages. This should correct the display of the isOpen control.

How and where has this been tested?

Please tag yourself on the tests you've marked complete to confirm the tests have been run by someone other than the author.

Validation steps

• Pull down the branch to run locally or visit the deploy preview
• Visit the dialog docs page.
• In the Properties table towards the bottom of the page, verify the "Open" control is capitalized. It should not be displayed or formatted like a variable (i.e. isOpen).

• Go to the default, fullscreen, and fullscreen takeover story pages.
• Verify the same "Open" control is capitalized and not displayed like the variable on each story page.

Regression testing

Validate:

1. The documentation pages for at least two other components are still loading, including:

• The pages render correctly, are accessible, and are responsive.

2. If components have been modified, VRTs have been run on this branch:

• VRTs have been run and looked at.
• Any VRT changes have been accepted (by reviewer and/or PR author), or there are no changes.
