[chore] Add a tool to add versions to versions.json

What do we need to do?

Create a new yarn tool to add new versions to data/versions.json. Ideally this should also create the skeleton version file. The tool usage could look like:

// Add a major release version.
yarn version add-version [name] "[releaseDate]" "[generalEndDate]" "[securityEndDate]" --lts
yarn version add-version 4.1 "14 November 2022" "13 November 2023" "10 November 2025" --lts

// Add a release to the version.
yarn version add-release [name] [versionnumber] "[releasedate]" [--upgradepath="https://..."] [--minor]
yarn version add-release 4.0.2 2022041900 "11 July 2022"

// Update the date of a version.
yarn version update-date [name] [--release-date="[date]"] [--general-date="[date]"] [--security-date="[date]"]

We should create a template in src (or somewhere else..?) to use in general/releases/[majorVersion].md or general/releases/[majorVersion]/[minorVersion].md.

Start by inspecting data/versions.json and the existing project tooling, then locate how documentation files under general/releases are generated or maintained. Define the commands and arguments from the examples, including version and release updates, LTS dates, upgrade paths, and templates in src or another suitable location. Done means the tool updates versions.json and creates the requested version or release skeletons.
