Fixes
https://github.com/payloadcms/payload/issues/11359#issuecomment-2678213414
The link element by using startTransitionRoute and manually calling
router.push would technically cause links to be clicked twice, by not
preventing default browser behaviour.
This caused a problem on clicking /create links as it hit the route
twice. Added a test making sure Create new doesn't lead to abnormally
increased document counts
Changes:
- Added `e.preventDefault()` in our Link element
- Added `preventDefault` as an optional prop to this element so that
people can handle it on their own if needed via a custom `onClick`
