doc: remove Gitter badge from README

Trott · Trott · commit cb11574b0b68 · 2017-05-29T08:35:41.000-07:00
Remove the Gitter badge.

Gitter is not supported by us. We use IRC channels on Freenode. Having
the Gitter badge is confusing because we list different resources
later in the doc and never mention Gitter.
