Several smaller code changes to improve type information and remove now
unneeded code structures based on improvements to both Node.js, TypeScript,
and underlying dependencies.
Updates for all angular.io links to the new angular.dev domain. Additionally, adjustment to new resources where the equivalent does not exist on the new site (e.g. Tour of Heroes tutorial)
G3 is now using RXJS version 7 which makes it possible for the CLI to also be updated to RXJS 7.
NB: this change does not remove all usages of the deprecated APIs.
Closes#24371
The `esModuleInterop` option is recommended to be enable by TypeScript and corrects several assumptions TypeScript would otherwise make when importing CommonJS files.
This option change helps ensure compatibility as packages move towards ESM.
