Upgrade and cleanup dependencies

[mikeharder]

• Remove unnecessary dependencies (many already transitive deps)
• In rulesets, move some deps from dev to runtime
  • May have worked in practice as dev deps, but was technically incorrect
• Upgrade all dependencies to latest major, except for these which require reactions to breaking changes:
  • typescript
  • @apidevtools/json-schema-ref-parser
  • vscode-jsonrpc
  • rollup, @rollup/plugin-commonjs, @rollup/plugin-json
  • jest, ts-jest, @types/jest
