Add pgp public key and refer to it in our security disclosure method

The idea behind this is to make sure people that choose to use email to let us
known about a potential security issue in Pidgin encrypt the content of the
emails using a set of pgp keys of trusted Pidgin developers. For now we only
have the pgp key of grim but more keys can easily be added later on.

At the same time, since Hugo does not currently have a built-in shortcode for
linking directly to static resources, I had to add a new shortcode for doing so

Testing Done:
Ran `dev-server.sh` and made sure content looked as intended and links worked.

We [recently released]({{<ref "post/2.14.5-released.md">}}) Pidgin 2.14.5
and mentioned in that post that we changed the default IRC network in Pidgin
from Freenode to Libera.chat. We've also posted on Reddit, Twitter, and
Facebook that we established `#pidgin` on Libera.chat and aim to meet our users
"wherever they may flock." As part of those posts we said we were monitoring
the ongoing situation, implying that we would take whatever we felt would be
appropriate action when necessary.
Yesterday (2021-06-15), Freenode threw away its decades of history. All user
and channel registrations were removed. All active connections to the "old" IRC
infrastructure of Freenode were terminated, forcing everyone onto the "new"
Freenode. As part of this, Pidgin developers' nickname registrations and, in
fact, `#pidgin`'s registration too, were lost. This is the ultimate outcome of
what was described as a "hostile takeover" of the Freenode IRC network some
weeks ago.
We have re-registered `#pidgin` on the new Freenode infrastructure and fully
intend to maintain our presence on the new Freenode. However, as a result of
these Freenode shenanigans and the overall general movement of the open source
software community away from Freenode, we decided that we will now consider our
presence on the Libera.chat network to be our "official" IRC presence.
Additionally, we also registered `#pidgin` on the OFTC IRC network and are
maintaining a presence there.
You will now notice that the IRC link on the side bar has been moved to our
[contact]({{< ref "contact#chatrooms" >}}) page and now points to Libera.chat's
web chat and that we've removed the Freenode links and information
on our [contact]({{< ref "contact#chatrooms" >}}) page. This is in keeping
with our decision to make Libera.chat our "official" IRC presence.
We aren't leaving Freenode as a project, although some people who used to be
stalwart presences in `#pidgin` there may not be present anymore. We're going
to continue maintaining our presence there as long as the network is not
hostile to our presence. We continue to aim to meet our users wherever they
may flock.
