determine minimum system requirements

[DerekNonGeneric]

This applies to both production and development. Some hints are seen below.

MSNV policy: Minimum Supported Node.js Version
MSRV policy: Minimum Supported Rust Version

This ties into the minor and patch release policy tentatively discussed at unicode-org/icu4x#2715.

If we want to support other runtimes, maybe avoid having something like: https://twitter.com/jarredsumner/status/1577176105659731968. Suggest reading https://medium.com/the-node-js-collection/maintainers-should-consider-following-node-js-release-schedule-ab08ed4de71a, but perhaps taking it with a grain of salt.

According to a talk on the matter given a couple of days ago, we should still be supporting Node.js v14.x named Fermium.

For development using VS Code Devcontainers: https://code.visualstudio.com/docs/remote/containers#_system-requirements

Run github/codeql-action/autobuild@v2
  with:
    token: ***
    matrix: {
    "language": "javascript"
  }
  env:
    CODEQL_ACTION_RUN_MODE: Action
    CODEQL_ACTION_VERSION: 2.1.31
    CODEQL_ACTION_FEATURE_SARIF_COMBINE: true
    CODEQL_ACTION_FEATURE_WILL_UPLOAD: true
    CODEQL_ACTION_ANALYSIS_KEY: .github/workflows/codeql-analysis.yml:analyze
    CODEQL_WORKFLOW_STARTED_AT: 2022-11-11T07:25:29.338Z
    CODEQL_ACTION_FEATURE_MULTI_LANGUAGE: false
    CODEQL_ACTION_FEATURE_SANDWICH: false
    CODEQL_RAM: 5920
    CODEQL_THREADS: 2

This may be interesting wrt the amount of RAM necessary for development (at least publishing).

I have continued w/ determining the development environment's minimum system requirements in this repo's wiki.
