Title

chore: enable typescript docs verification for example snippets

Description

This had been disabled leading to some erroneous Typescript snippets in the examples

Notes & open questions

Change checklist

• I have performed a self-review of my own code
• I have made corresponding changes to the documentation if necessary (this includes comments as well)
• I have added tests that prove my fix is effective or that my feature works

This is a hack for now given that typescript docs verifier relies on the exports for its check

There are some good doc improvements in here so I'd like to merge this but where is the bit of the PR that re-enables doc-check for TypeScript snippets like the title says?

Strange, I had assumed CI was running the command and that the actual doc-check command was a no-op, which is what this PR addressed. Turns out the CI was also a no-op as well, so I pushed a commit to fix in de72f20.

It also turns out a recent typescript upgrade broke ts-node which typescript-docs-verifier depends on so I am using a fixed Typescript version until that gets resolved and the ts-node fix should bubble upstream.
