chore(dependencies): bump TypeScript to 3.6

Updating the compiler version resolves some major performance problems
triggered by the Glimmer type definitions. Unfortunately, it also causes
some noise due to [glimmerjs/glimmer-vm#946], but that should be fixed
in an upcoming release of the `@glimmer/*` packages, and it does not
cause internal issues for this package.

[glimmerjs/glimmer-vm#946]: glimmerjs/glimmer-vm#946
