Upgrade root packages

[corymharper]

This pull request upgrades every package at the root level to the latest version, and makes any needed changes to deal with breaking changes, including adding new required packages.

Changes that affected us:

• Various versions of node are no longer supported by packages we use in development, generally speaking only the versions 14 (LTS Maintenance), 16 (LTS), and 18 (Current) are now supported. This required a change to the test runner configuration.
• JSDOM is no longer included by default as a jest environment and has to be installed separately

There are a number of places that still use 14.x instead of 16.x in the main.yml file.

[WesCossick]

Actually, can we try using lts/* instead of 16.x and current instead of 18.x, so that we don't have to upgrade that in the future? Be sure to replace all 14.x with lts/* since that was the intent at the time.

If this works, we probably want to apply this to our other OSS packages...

I think the build might be failing due to this not being set to true? https://github.com/actions/setup-node/blob/main/docs/advanced-usage.md#check-latest-version
