Closes #973

Context / Background

New attempt to have more consistent npm installs.

What change is being introduced by this PR?

Using fixed versions for npm packages in hopes of having more consistent installs and changes to lock files for new dependencies. Also updating checks.yml actions and node versions. Added an .npmrc file with save-exact=true so we don't have these issues in the future.

How will this be tested?
