Vincent Ambo 875ef0a605 fix(web/blog): make base URL configurable for atom feeds
This was previously hardcoded to tazj.in, which is not going to work
of course.

Instead it now takes the blog config which has a new baseUrl
parameter. For ease of use, the configs of my and the TVL blog have
been moved into a location that is accessible in the tree for reuse.

Welcome to **The Virus Lounge**. We're a group of people who got
together in 2020, when we felt that there was not enough
spontaneous socialising on the internet.
Because of our shared interests in topics like **build systems**
and **monorepos** we started working on code together, in our
monorepo called the *depot*.
Feel free to explore the tech we have built so far, all our
systems are linked in the footer.
We mostly hang out on IRC. You can find us in [`#tvl`][tvl-irc]
on [hackint][], which is also reachable [via XMPP][hackint-xmpp]
at [`#tvl@irc.hackint.org`][tvl-xmpp] (sic!).
Hackint also provide a [web chat][tvl-webchat].

## Where did all these people come from?
It's pretty straightforward. Feel free to click on people, too.
