Mention equivalent Play Store webpage

As F-Droid on my Fairphone 4 own LineageOS 22.2 opens F-Droid app URL in F-Droid app, but for people not having the app being able to fallback to Play Store may be nice, but this would still advertize the play Store.

My aim is to send F-Droid link to apps to people, and they may use Play Store if they don't have F-Droid or prefer to use the Play Store.
