[Tails-dev] Missing bit of information on your website

Hello:

I was looking over the download and verification instructions and noticed
that it might be helpful to add an additional step in the Command line
instructions under "See instructions for basic OpenPGP verification.
<https://tails.boum.org/install/download/index.en.html#install-inc-steps-download.inline.basic-openpgp>"
that
describes how to import the Tails signing key.

Thank you,
Sunny
