This change provides more fine-grained warnings during the `update-module-and-target-compiler-options` migration for V10.0 in the event a TypeScript configuration file could not be updated. The `JSONFile` utility class was also augmented to directly throw when created to ensure that the `content` property is always initialized.
TypeScript 3.9 requires tslib 2.0.0, with this change we;
- Update tslib existing and new workspaces to use tslib 2.0.0
- Update new and existing libraries to use tslib 2.0.0 as a direct depedency.
Tslib version is bound to the TypeScript version used to compile the library. Thus, we shouldn't list `tslib` as a `peerDependencies`. This is because, a user can install libraries which have been compiled with older versions of TypeScript and thus require multiple `tslib` versions to be installed.
