Fix structure of generic snippet feature (#74932)
* Fix struture of cli/doc.py snippet code.

A couple releases ago, cli/doc.py was modified to mostly conform to the
data processing pipeline steps.  format_plugin_doc() was the biggest
exception in that refactor.  When the snippet code was made generic
instead of being only for modules, the new code should have conformed to
the data processing pipeline too.

* Move the decision to output a snippet to the run() method alongside
  the decision to output a listing versus plugin_docs.
* Move the test for invalid plugin_types to the run() method as it
  affects all snippets in this run, not just a single snippet. (-t can
  only be specified once)
* Rename get_snippet_text() to format_snippet() as:
  * This is the data formatting step
  * The format_snippet() name matches with its conceptual sibling,
    format_plugin_doc().
* Use ValueError inside of format_snippet() to flag unrecoverable errors
  formatting a single snippet.
* Emit a warning when format_snippet() raises ValueError and continue to
  the next snippet.
* If the yaml(?) or toml inventory plugin is specified for snippet output,
  raise ValueError() so that the user sees a warning instead of simply
  seeing blank output.
* Do not modify arguments passed into format_snippet().  This is the
  formatting step so data should not be modified.
* Change _do_yaml_snippet() and _do_lookup_snippet() to operate side
  effect free.
* Fix raising of exceptions when formatting requred options for snippets.

* Unrelated: Use to_text() instead of to_native when calling
  display.warning(). to_native() is used for raising exceptions.  Not
  for display methods.

* Add a changelog
