Spina is now using TypeScript 5.3.3 instead of 4.9. This doesn't

currently impact anything, and in fact the built files are the same

between versions, but it will help us maintain compatibility with

consumers, stay on top of newer releases, and eventually integrate with

features like Stage 3 decorators.
It did catch some type issues, which have been addressed in prior

changes.
package-lock.json has also been updated for the latest version of all

pinned dependencies.

Unit tests pass.
Built new deliverables and diffed them against a build from the prior set

of dependencies. There aren't any changes.
