Make release notes links more useful

Right now, the Release Notes link in the About window and the What's New command in the Help menu both take you to the top of https://releases.1password.com/mac/early-access/. Since I actually want to know what's changed in each release, that means I have to scroll down past the long post with all the general v8 details. But since I obviously already have v8, I don't need to read that every time.

Please make these in-app links go directly to the actual release notes (e.g., https://releases.1password.com/mac/early-access/#1password-for-mac-8.4.0-53). The page already has links for each set of notes, you just need to use those in the app. It will make post-release life that much easier for us. :-)
