Update ng-flutter to resolve security alerts (#1985)

The main goal was to resolve some security alerts being triggered on the
repository, but I also updated angular and verified the sample continues
to work.

Resolved security alerts:

- https://github.com/flutter/samples/security/dependabot/3
- https://github.com/flutter/samples/security/code-scanning/45
(https://github.com/advisories/GHSA-c2qf-rxjj-qqgw,
