Add sponsor button linking to Google Play

[TheLastProject]

After you enable this on your repository, it'll show a sponsor button left of watch which links to Google Play. More info on https://help.github.com/en/github/building-a-strong-community/displaying-a-sponsor-button-in-your-repository.

Also, may I suggest signing up for GitHub Sponsors? Right now they have no fees at all and match any sponsorship. You could set a 6 Euro tier for a pro key maybe and tell people to email you if they use it so you avoid all Google's fees? Up to you, of course :)

@TheLastProject thanks for the suggestion. I have added the file with another link. I don't see the sponsor button/link yet, but maybe that is because I am the owner of the repo?

I will look into GitHub sponsor.

You'll still need to enable it for your repository under settings: https://github.com/M66B/FairEmail/settings. It's the "Sponsorship" button.

And wrap the link in quotes according to the docs. Both done and there is now a lovely heart icon ;-)

Multiple links is possible too, so I have added the Play store link too.

I didn't know this was possible, so thanks.

Sponsoring has been enabled for NetGuard, XPrivacyLua and FairEmail for about a week, but there are no sponsors yet :-(
