OGP / Twitter card

[jinjor]

I shared my package on Twitter but it was not appealing so much.

I suggest adding some OGP information like this:

  <meta property="og:type" content="website">
  <meta property="og:site_name" content="Elm Packages">
  <meta property="og:title" content="elm-xml-parser">
  <meta property="og:url" content="http://package.elm-lang.org/packages/jinjor/elm-xml-parser/latest/">
  <meta property="og:image" content="/assets/elm_logo.svg">
  <meta property="og:description" content="XML Parser for Elm">

Thanks for the issue! Make sure it satisfies this checklist. My human colleagues will appreciate it!

Here is what to expect next, and if anyone wants to comment, keep these things in mind.

Thanks for the suggestion! I did not know about this, but this definitely will make things nicer!
