[PATCH v3 2/3] doc: rephrase terminology in dts.rst

[Dean Marx <dmarx@iol.unh.edu>]

Rephrase some of the DTS tool/term definitions to be more concise.
These sections were unnecessarily verbose and can be conveyed
in a clearer way.

 There are two tools used in DTS to help with code checking, style and formatting:
 
-* `ruff <https://astral.sh/ruff/>`_

-  An extremely fast all-in-one linting and formatting solution,
-  which covers most if not all the major rules such as:
-  pylama, flake8, pylint etc.
-  Its built-in formatter is also Black-compatible

 These two tools are all used in ``devtools/dts-check-format.sh``,
 the DTS code check and format script.
