Update dependencies to React 18, Node 20, TS 5.2, etc.

[dylans]

Description

Slate is falling behind on its dependencies. This wave of work updates core dependencies, a partial fix for #5507.

It does not (yet) address updating the build to output both CJS and ESM versions, and does not yet make any efforts to improving the internals to use improvements introduced in React 17 and 18.

However, this is a potentially big breaking change if you're using pre React 18 or older versions of TS.

Issue
Partial fix for #5507
