chore(typescript): disable exactOptionalPropertyTypes

This setting is causing problems for us with one package we'd like to
use:

#1012 (comment)

and is also preventing us from migrating to TypeScript 5 due to an
upstream issue in `react-router` that's been unaddressed for almost a
year:

#898

There were no objections to disabling it, so we do so in this commit.
(There is one minor code change required as a result, just an
additional optional property check on a `onNodeClick` handler in our
React Flow wrapper.)
