[DO NOT MERGE] Manage all records in tahoe-lafs.org zone on Hetzner with Tofu

[btlogy]

Closes of #56

This PR is completing the provisioning of the DNS zone for tahoe-lafs.org hosted by Hetzner with all its existing records.

Once deployed, nothing will actually change for the users on internet. But this new zone will allow for a smooth transition if/when the delegation will be changed from Gandi: see trac#4162 for more info.

Hopefully, this will help to make progress on a few open issues, starting with the ones related to MoveOffTrac:

• Deploy and configure Forgejo and its requirements on webforge #44
• Configure webforge to host the new landing page and allow its automatic deployment #45

NOTES:

• We still need a separate issue to deal properly with the credentials used to interact with Hetzner (user, password, 2FA and token).

I'm pretty sure we are missing some records. But that the whole point here: we should have them all here for community to see.

Thus, we need to compare the records in this PR with a fresh export/dump from Gandi, which today can only be provided by @warner or @meejah.

Heads-up following the initial ask from trac#4162, we are still unsure if we get an export of the DNS records as they stands today.

More info on #56...

@meejah has provided the export from Gandi and I've added some missing records (e.g. builmaster and wormhole).
