chore: add npm script to report deprecated but unremoved api

[sgtcoolguy]

Optional Description:
This adds an npm script: npm run deprecations which will parse the apidocs and find types/properties/methods we've marked as deprecated but have not yet marked as removed.

Lists the APIs in order from oldest deprecated version to newest. This should give a good listing for things we need to get rid of in breaking change releases.

Gives me:

Relates to #11362

Note that I didn't have it check method parameters or events.

cc @janvennemann this probably should go into appcelerator/docs-devkit with a parameter to filter out results with a new-enough version (i.e. when we lint modules or sdk api docs, we can pass in an argument and say, show me all results so long as the deprecated since version is < 8.0.0)

[sgtcoolguy]

Also possibly useful? another variant that finds deprecated and removed APIs older than version X for potential removal from the apidocs altogether (i.e. we probably don't need to document APIs that have been removed 2/3+ years ago any more)

[sgtcoolguy]

OK, followed it up with another script that can show the "old" removed apis to give us a listing of things we should consider dropping from the YML docs altogether. For now it's set to consider any API removed prior to 7.0.0 release.
