Update dependencies and force-update qs (#6440)
* Update dependencies and force-update qs

This is mainly an attempt to get rid of as many resolutions as possible
since it seems they are unnecessary except for qs (according to yarn/npm
audit).

For qs use 6.9.7 since Express is using 6.9.6 and that matches the most
closely.

Also add overrides since this is npm's version of yarn's resolutions and
we need it for the shrinkwrap to generate with the right dependencies.

Decided to keep pinning @types/node as well although I am not sure it is
necessary.  Express is pulling in v20 types.  Since this is
development-only we only need it in resolutions.

* Run formatter

Some rules seem to have changed with the dependency updates.

* Replace deprecated bodyParser.json() usage

* Audit npm shrinkwrap as well

* Skip installing dependencies in audit

It seems the tools only require the lock files.

* Fix tests when using ipv6

* Add missing openssl dependency to flake
