originalKeywordKind has been deprecated

[pmcelhaney]

Got this error after upgrading to TypeScript 5.2:

DeprecationWarning: 'originalKeywordKind' has been deprecated since v5.0.0 and will no longer be usable after v5.2.0. Use 'identifierToKeywordKind(identifier)' instead.

Looks like a fairly straightforward fix. I'll send a pull request shortly.

Here's a work-around until it's fixed: Install patch-package, add "postinstall": "patch-package" to your npm scripts, and copy this code to a file named ./patches/tsutils+3.21.0.patch.
