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)
Code related to decoding buffers into strings and parsing content into JSON can now be removed by using the
support provided directly from the Tree instance for the executing schematic.
By using the `strings` re-export from `@angular-devkit/schematics` instead of from `@angular-devkit/core`,
the number of imports from `@angular-devkit/core` has been reduced and lowers the direct dependency count
for many of the individual schematics.
With this change we removed several deprecated `@schematics/angular` deprecated options.
BREAKING CHANGE:
We removed several deprecated `@schematics/angular` deprecated options.
- `lintFix` have been removed from all schematics. `ng lint --fix` should be used instead.
- `legacyBrowsers` have been removed from the `application` schematics since IE 11 is no longer supported.
- `configuration` has been removed from the `web-worker` as it was unused.
- `target` has been removed from the `service-worker` as it was unused.
Currently when using `ivy-ngcc` it will print out a warning
```
Failed to read entry point info from //node_modules/@schematics/angular/workspace/files/package.json with error SyntaxError: Unexpected token < in JSON at position 1121.
```
Fixes#13378
This aligns options that do the same thing:
1) `skipSpecs` and `spec` has been deprecated in favor of `skipTests`.
2) `styleext` has been deprecated in favor of `style` since the latest is two words.
Fixes#12784
