beorn7 1071c82b42 docs: counter vs. gauge histogram behavior with +/-

This mostly handles the cases mentioned in #16576. However, there are
some related changes in here, too:

- Some line formatting to avoid lines longer than 80 characters.

- Establish in basics.md that histograms have a counter vs. gauge
  "flavor" that is also stored in the sample and not just by
  convention as for float samples.

- Add the documentation of the unary minus, which was missing so far.
  This require a bit of restructuring.

- Cleaned up a few references to "Prometheus" that should better refer
  to "PromQL" (and "Prometheus's query language" → "PromQL" etc.).

I decided to not explain in all detail when and how PromQL detects an
incompatible counter reset. The spec is linked from basics.md, so the
minority that might be interested in this can still look it up.
