Oauth2-proxy: Exclude go version from asset link

[max-wittig]

Expected Behavior

Other projects just include the version of the dependency itself, so that it easily be bumped

Current Behavior

Oauth2 proxy includes the go version, which as I user of oauth2-proxy, I don't care about.

Possible Solution

Exclude go version from release asset

E.g. instead of

- https://github.com/oauth2-proxy/oauth2-proxy/releases/download/v5.1.1/oauth2_proxy-v5.1.1.linux-amd64.go1.14.2.tar.gz
+ https://github.com/oauth2-proxy/oauth2-proxy/releases/download/v5.1.1/oauth2_proxy-v5.1.1.linux-amd64.tar.gz

Context

E.g. when using ansible to deploy, you might have the version of oauth2-proxy in your group_vars, like this

oauth2_proxy_version: "5.1.1"

which ansible uses then to complete the jinja2 template

https://github.com/oauth2-proxy/oauth2-proxy/releases/download/v{{ oauth2_proxy_version }}/oauth2_proxy-v{{ oauth2_proxy_version }}.linux-amd64.go1.14.2.tar.gz  # the go version makes this not work

I don't really know why we do this tbh, I know it was done before we adopted the repository from Bitly and I guess we just carried it on.

I don't really see an issue in changing it, except from it could be considered a breaking change.

@syscll @gargath I know you both have had opinions on this stuff before, any thoughts?
