fe8074c8c3 Refuse to parse v2 onion addresses without deprecated_apis 
Tor v2 hidden services have been deprecated for a while:
https://blog.torproject.org/v2-deprecation-timeline .

This prevents user from being able to set them in the configuration
and to connect to them while still letting us be able to parse them
for gossip.

Changelog-Deprecated: lightningd: v2 Tor addresses.  Use v3.  See https://blog.torproject.org/v2-deprecation-timeline.

7bd6b5a108 readme: fix ubuntu installation instructions 
I have verified that this results in working bitcoin core and c-lightning on fresh Ubuntu 20.04 server installation.

This is also consistent with instructions in doc/INSTALL.md

Fixes:  #4538

f798fb1dd6 Clearer RETURN VALUE 
When I read the RETURN VALUE the first time, I didn't realize this command produces (or recreates) the psbt that I need.  The change I made makes that more obvious when it's presented as a hit by GH for a search for psbt.

cb7e7b293f added FAQ on getting a PSBT 
It may also be appropriate to update the description of utxopsbt so that the search hits for "psbt" here on github make it clearer that utxopsbt returns what you're seeking.  I'll make that part of this pull request too.
