Bump txtorcon from 23.0.0 to 23.11.0

[kristapsk]

In #1567 we updated to 23.0.0, not 23.5.0, because that was the last version supporting Python 3.7. Now that Python 3.7 support is dropped with #1639, can upgrade to latest.

Changes in 23.5.0:

• twisted.web.client.Agent instances now use the same HTTPS policy by default as twisted.web.client.Agent. It is possible to override this policy with the tls_context_factory= argument, the equivalent to Agent's contextFactory= (Thanks to Itamar Turner-Trauring)
• Added support + testing for Python 3.11.
• No more ipaddress dependency

Changes in 23.11.0:

• Fix test-failures on Python 3.12
• Particular GETINFO hanging (When tor process exits unexpectedly tor.protocol.get_info hangs meejah/txtorcon#389) (ultra-long lines over 16KiB caused problems in the protocol)
• Use built-in mock only (https://github.com/jelly)
• Remove incremental (https://github.com/gdrosos)

Basically, not much changes, but fixed bug, dropped dependencies and better support for Python 3.11 and 3.12 is good enough reason to merge for me.

Test suite passing is good enough here, but may be worth manually checking joinmarketd and particularly payjoin CLI functioning is correct (it's very unlikely in this case, but we do have some monkeypatching of txtorcon in our Tor code that could easily break in an update).
