ci: remove typescript 3.7 patches in material-unit-tests job (#34863)

Previously, we added patches to the `angular/components` repository in
the `material-unit-tests` job in order to be able to run their tests
with TypeScript 3.7. This is no longer needed since the components
repository updated to Ts 3.7 already. Hence we can remove the patches.
