chore: update dgeni-packages

[andrewseguin]

The dgeni packages was relying on an older version of typescript, causing issues with enum equality here:

  const directiveDecorator = declaration.decorators
    .filter(decorator => decorator.expression)
    // TODO(devversion): fix this cast
    .filter(decorator => (decorator.expression.kind as any) === SyntaxKind.CallExpression)
    .find(decorator => (decorator.expression as any).expression.getText() === 'Component' ||
                       (decorator.expression as any).expression.getText() === 'Directive');

Closes #11177

LGTM

I see that you just added the pr: merge ready label, but the following checks are still failing:
     status "branch manager" is failing
     status "ci/circleci: build" is pending
     status "continuous-integration/travis-ci/pr" is pending

If you want your PR to be merged, it has to pass all the CI checks.

If you can't get the PR to a green state due to flakes or broken master, please try rebasing to master and/or restarting the CI job. If that fails and you believe that the issue is not due to your change, please contact the caretaker and ask for help.

Needs to be target: patch if we want it to apply to the docs on the weekly patch release
