e1765d8b04 doc: update tor.md address examples from onion v2 to v3 (Jon Atack)
Pull request description:
It looks like `doc/tor.md` could use some updates and improvements, not only for Tor v3, but also for setting multiple addresses with `-externalip` (see the conversation from http://www.erisian.com.au/bitcoin-core-dev/log-2020-09-16.html#l-39), how to see information about your Tor config via Bitcoin Core, and other improvements.
Closes#19924.

This is a follow up to https://github.com/bitcoin/bitcoin/pull/19638 that left some deprectaed "hidden service/server" naming occurences.
It also shall make the chapter titles regarding creation of onion services stringent and easy to read and distinguish.
It removes the one and only reference to the testnet (here the testnet onion service port), as it is not explained that it references to the testnet and I do not know why it is mentioned there. It is only confusing. Also, as said, the testnet is not referenced at any other place in this document.
For a couple of years, Tor documentation has made
the term hidden service obsolete, in favor of onion
service.
This PR updates all the references in the code base.
Starting bitcoind with `-onlynet=onion` immediately after adding bitcoind user to debian-tor group will yield the following notice on debug.log:
"tor: Authentication cookie /run/tor/control.authcookie could not be opened (check permissions)"
Elaborate on the need to re-login to ensure debian-tor group has been applied to bitcoind user after:
sudo usermod -a -G debian-tor username
Verification can be done via `groups` command in shell.
The current documentation leads the reader to think `hash-password` is an other option.
This change is less confusing and make it clear how to use this option.

[Docs] Add version footnote to tor.md
Added note to section 2, part -edits to `/etc/tor/torrc`- indicating this is only required for Tor version 0.2.7.0 and older, since section 3 states it is valid for Tor version 0.2.7.1 and newer. Added ref link from section 2 version footnote to section 3. Re-styled headings to work on GitHub -alternate heading style markup creation issue with numbered headings and thus headings and automatic heading links are broken-

> This new feature is enabled by default if Bitcoin Core is listening, and a connection to Tor can be made. It can be configured with the -listenonion, -torcontrol and -torpassword settings. To show verbose debugging information, pass -debug=tor.
But it is correct to say that the feature is enabled *regardless* of whether a connection to Tor can be made.
I propose to clarify that so that users can eliminate these in their logs (when `listen=1` and no Tor).
And I think it's okay to clarify about the `listen` option, because on several occasions when I read this before I always assumed `listening` meant `server=1` which cost me a lot of time in troubleshooting.

### What version of bitcoin-core are you using?
0.12.1
Seems like there are a lot of advertised testnet HS nodes that
don't actually work. Lack of the testnet port on the example
HS config might be one reason.
I've seen users confused multiple times thinking they
should be using -tor to set their tor proxy and then
finding in horror that they were still connecting to
the IPv4 internet.
Even Jeff guesses wrong about what the knob does, so
I think we should rename it. This leaves the old
knob working, we can pull it out completely in a
later release.
