Upgrade Weaver-UI-Core (2.2.2-rc.8)

[x] Upgrade Weaver-UI-Core (use "@wvr/core": "2.2.2-rc.8" until release is available)
[x] Upgrade all dependencies with vulnerabilities
[x] Passes CI (all tests if no CI configured)
[x] Provides a Dockerfile based on this (rough) spec
[x] Replace grunt with webpack - at least requires to add or modify .wvr/build-config.js, package.json, and index.html. (blocked by https://github.com/TAMULib/Weaver-UI-Core/issues/182)

If a certain dependency upgrade or deprecated code replacement ends up being large in size, create an issue.

Document procedure followed to do the upgrades on the app - insofar as it varies from the previously documented apps
