Mark the two community add-ons as community (#92)

Every addon.json claimed origin "appdevforall" and App Dev For All as
the author, so the gallery's Community filter matched nothing and two
contributors were uncredited on their own cards.

appdevforall.org/plugins names the third-party contributions, and the
repository agrees with it:

  Icons Repository  - Omar Haidar (README credits, upstream repo)
  Flutter Templates - RJ Ali, from an idea by Raju Kumar
                      (README "Credit", add-on page byline)

Both are now origin "community" with the contributor as the author, and
the description carries the credit line the card shows.

RJ Ali has no public profile in the repository, so author.url is empty.
Fill it in if he has a GitHub account.
