Hacktober-update for all dependencies

[jeroenheijmans]

Hacktober is a great excuse to once again do some hygiene updates and make sure all dependencies and devDependencies are up to date. I'm always happy to accept PRs that bring the repo up to date, but for hacktober it seems sensible to create an explicit issue for it, especially for those who are looking to get their very first open source PR in! (So feel free to skip this issue if you already know the ropes of PRs....)

Note that you can locally run npm run e2e to see if your update worked, and any PR will also show the results of Actions (automated build).

PS. There's a sample-angular-oauth2-oidc-with-auth-guards channel in the contributing.today Discord where I'll be if anyone has hacktoberfest-related questions!
