Release links include .gz extension but files are not GZipped

[rafaelmagu]

Links to the binaries in the 3.0.0 release include .gz extensions, when in fact the links are just TAR files.

Expected Behavior

$ curl -sL https://github.com/pusher/oauth2_proxy/releases/download/v3.0.0/oauth2_proxy-v3.0.0-0-g7887272.linux-amd64.go1.11.tar.gz | tar zxvf -
release/oauth2_proxy-linux-amd64

Current Behavior

$ curl -sL https://github.com/pusher/oauth2_proxy/releases/download/v3.0.0/oauth2_proxy-v3.0.0-0-g7887272.linux-amd64.go1.11.tar.gz | tar zxvf -

gzip: stdin: not in gzip format
tar: Child died with signal 13
tar: Error is not recoverable: exiting now

Possible Solution

Remove .gz from the links, or GZip the TAR files.

Steps to Reproduce (for bugs)

1. Download one of the binaries.
2. Attempt to gunzip it.

Context

$ file oauth2_proxy-v3.0.0-0-g7887272.linux-amd64.go1.11.tar.gz
oauth2_proxy-v3.0.0-0-g7887272.linux-amd64.go1.11.tar.gz: POSIX tar archive

Your Environment

Ubuntu Linux 18.04.

Apologies, they were meant to be zipped. The problem will be in the Makefile release target, I'll double check it and fix. Thanks for bring this to our attention!
