Dependency updates

[tsmock]

This is largely a PR to updated react-scripts dependencies.

Of specific note for downstream users:

• @babel/core: Min version now 7.22.9. Note: 8.x will have breaking changes.
• @svgr/webpack: Min version now 8.0.1, v6 migration docs indicate this might be ESM only; I have not verified this. I might have to roll it back to a v6 version.
  • https://react-svgr.com/docs/migrate/
  • Requires webpack 5 or later which we are already doing
  • Uses SVGO v3
  • Does not merge configuration anymore
  • plugin-jsx no longer included by default
• fill in rest of react-scripts update notes

Reasons for updating dependencies:

• Update Jest from v27 to v29
• Make it easier to track down and fix bugs
