[REQUIRED] Step 1: Describe your environment

• Xcode version: 13.0
• Firebase SDK version: 8.8.0
• Installation method: CocoaPods
• Firebase Component: DynamicLinks

[REQUIRED] Step 2: Describe the problem

Steps to reproduce:

Try to use DynamicLinks.dynamicLinks().handleUniversalLink(url) on a shortlink for a Firebase generated DynamicLink.

Links of the format https://*.page.link/test do not match the new regex that was implemented in this commit 85864c6

Full links of the format https://*.page.link/?link=https://google.com/test do work correctly.

They are working correctly in 8.7.0.
