Use Github hosted assets in emails sent by Fleet (#2090)
This change allows the images in Fleet emails to load properly from any
device with connectivity to github.com. Previously, emails might try to
load resources from a Kolide server not accessible from the email
client.

The asset URL will be based on the most recent git tag to accomodate
backwards-compatibility if the assets in the repo change.

Closes #1471
