vscode-ext: move to esbuild bundling, cleanup

This removes node_modules from dependencies all together fixing long
time issue with yarn putting only a subset of dependencies in the
extension source tree.

It as well makes extension footprint 15x smaller. (down to 2.3Mb)

Kinda fixes quantified-uncertainty#1162? It actually un-patches vsce though — it really is not
an issue it should be solving :D
