setup: update Tesla API section

Recent Tesla firmware changes effectively blocked TeslaUSB's ability to
keep the car awake during archiving, so remove the corresponding variables
from the config file and describe alternatives.

-# NOTE:  if you do this, it's highly recommended that you set up 'PIN to Drive'

+# Recent car firmware turns off USB ports very shortly after you get out of
+# the car, and changes to the Tesla API make it impossible for TeslaUSB to
+# keep the car awake or turn on Sentry mode in order to keep the USB ports
+# powered. This means that to keep the USB ports powered so that TeslaUSB
+# can finish archiving you need to turn on Sentry mode manually using the
+# Tesla app (or have it enabled by default for your home location).
+# Turning on Camp mode keeps the USB ports powered as well, but turns on
+# climate control which uses a lot of power.
+# If you turn on Sentry or Camp mode manually, you should probably set up
+# one of the notification mechanisms (see above) to let you know when
+# archiving finishes, so you can remember to turn Sentry/Camp mode off again.
+# It has been reported that some car models keep the USB ports powered
+# while the car is charging.
+# You could also consider using a power bank or UPS hat to keep TeslaUSB
+# powered independent of the power state of the car's USB ports. See the
+# TeslaUSB wiki for more info.
 #
-# ALSO NOTE: having sentry mode enabled in your Tesla will keep your car awake.
-#   But, make sure you have not excluded your home in the sentry mode settings.
+# It may also be possible to use Tessie or TeslaFi to keep the USB ports
+# powered (both are paid services) by defining the variables below.

-# TeslaFi or Tessie Subscriber?
-#   If you're a TeslaFi or Tessie user, you may consider keeping the car awake using
-#   one of their APIs instead. The advantage is not having to expose Tesla's Token
-#   and other info in this file as plain text, which is a vulnerability (as
-#   noted above. 'PIN to Drive' is not necessary in this case.
-#   TeslaFi and Tessie's API token can easily be revoked and a new one generated at
-#   anytime. TeslaFi also allows selective command(s) enablement (e.g. disable
-#   uneeded commands), further decreasing vulnerability.
