Suggested changes for bluetooth information

[ingatellent]

Here are some suggested changes for the bluetooth page with information on how to avoid "random" disconnects (they are actually not random at all, but completely deterministic and expected).

restructured text doesn't like to render properly when codeblocks don't have a whitespace before them, but wont raise a warning or exception. I haven't tested to see if this renders properly as-is, but it's probably best to be consistent. There was also a spelling mistake that spellcheck made me aware of.

You've got this marked as a draft still, was there anything else it was waiting on?

I'm still testing the udev solution out in practice - there are sometimes disconnects with this solution anyway, I'm trying to confirm that this is the external device which disconnects (and then adding information on that).
I'm also considering adding a note about the fact that bluetooth keypresses in xochitl does not reset the sleep/slumber timer - which means that the device can go to sleep while your are actively interacting with it (but this is also true for the type folio key events, so might not belong here).
Finally I'm considering adding information about csl power -w wakelock_name:300000 which can put a wakelock with a timeout (which might be better for battery life) - but that also seems like it would fit best on a page with csl information.

I guess these things could be a separate PR except for the first comment.

I haven't got more time to dig deeper the next couple of weeks, so I think this could be merged now.
