Update dependencies to latest compatible versions

[jakebailey]

We haven't done this in a bit. Most of these updates we already have via lockfile, but some are major updates that are compatible.

After this, ncu says:

Checking /home/jabaile/work/TypeScript/package.json
[====================] 41/41 100%

 chai   ^4.4.1  →  ^5.0.0
 chalk  ^4.1.2  →  ^5.3.0
 which  ^3.0.1  →  ^4.0.0

Run ncu --target latest -u to upgrade package.json

chai is now ESM only and breaks our use.

chalk would now work, because we only use it in ESM contexts. But, upgrading it actually manages to increase the size of node_modules thanks to the pervasiveness of v4.

which's minimum node version is now Node 16, but we still support and build with Node 14.
