LP#2022939: update package-lock.json for Angular staff client

This patch serves to quell some warnings about deprecated
pacakges; it also removes some packages that were previously
removed from package.json.

As of 2023-06-05, the remaining two warnings during an
'npm install' look benign:

npm WARN deprecated @npmcli/move-file@2.0.1: This functionality has been moved to @npmcli/fs
npm WARN deprecated w3c-hr-time@1.0.2: Use your platform's native performance.now() and performance.timeOrigin.

To test
-------
[1] Remove node_modules from the Angular staff client and
    rerun 'npm install', then verify that the Angular staff
    client works as expected.
