Description

We had to introduce execa v5 to packages/plugin-types/src/package_manager_controller.ts, because it's the latest execa version that supports commonjs.

ref: https://github.com/sindresorhus/execa/issues/489#issuecomment-1109983390

This change makes the execa version in our repo inconsistent.

Once execa's latest version supports commonjs, we need to make its version consistent.
