Truncate the version string when linking to the documentation

The admin console would dynamically discover the version from the
InfluxDB server, but for patch releases, it included the patch in the
link to the documentation and that wasn't a valid link.

Truncate the version so the documentation url is correct since we only
do documentation for `major.minor`.
