Bug Description

For reproduction I have simply linked the v9 docs as the behaviour can already be seen there.

Actual Behavior

The title dialog for dialog without actions is not taking full row. Screenshot taken from the v9 docs, this wasn't the behaviour in a previous version looks like a regression to me.

To reproduce just open the first dialog in the v9 docs (https://react.fluentui.dev/?path=/docs/components-dialog--default)

Expected Behavior

The title should take the whole row if there are no actions.
