syntax: update keywords, functions and types. mark deprecations

puppet 8 has some new things and some things have disappeared. This
change updates the list of keywords, functions (core and stdlib) and
types, to reflect more modern versions of puppet and stdlib

I've also reworked some of the syntax group -> highlight group links to
have a richer context. For some examples:

* class, node, define and plan are marked as a "Structure" instead of
  "Keyword".
* contain, create_resources, include, hiera_include are marked as
  "Include" directives since they pull in more code
* a new syntax group puppetDeprecated now exists to remove highlighting
  from the deprecated resource types and functions. it should help to
  spot what needs to be changed.

Finally, I've also added the types and functions specific to puppet Bolt
