Fix github link in docs

[Tranquility]

Currently the value of current_version is latest and since there is no branch called latest github is returning a 404 error.

Ah. The {{current_version}} is now indeed broken, since we removed the tag 'latest'. But other tags, like v.0.5.3 will still work and I'd prefer to have the docs point to the documentation version they were built from.

Could you modify this to have a conditional, like so:

{%- if current_version == 'latest' %}
master
{% else %}
{{ current_version }}
{% endif -%}

note that the dashes (-) are just for not adding line breaks.

I changed it. Tell me what you think, I will happily change it again 😃
