Add a function that returns all known browser versions with Baseline data

[tonypconway]

It would be useful to be able to obtain a matrix of all browser versions known to this module with the following format:

{
  "browser": "chrome",
  "version": "89",
  "baselineYear": 2021, // which Baseline year feature set the version supports
  "widelyAvailableSupported": false, // whether the version supports the current WA feature set
  "releaseDate": "2021-03-02"
}

The matrix could also include extra data for downstream browsers, e.g.:

{
  "browser": "qq_android",
  "version": "14.2",
  "year": 2022,
  "widelyAvailable": true,
  "releaseDate": "2023-10-14", // or null if not available
  "engine": "Blink",
  "engineVersion": "109"
}

Also worth considering: run a daily job that publishes this data as a CSV either in the module or a github page within this repo.
