DITA-OT Homebrew formula for macOS

✨ Sean Molenaar (@SMillerDev) has successfully submitted a dita-ot formula to Homebrew with https://github.com/Homebrew/homebrew-core/pull/28762, which allows users to install DITA-OT on macOS via this popular package manager.

The brew formula excludes the Windows batch files (which are useless on macOS) and the legacy startcmd scripts, but is otherwise identical to the original distribution package.

When the package is installed via brew install dita-ot, Homebrew automatically downloads the latest version of the toolkit, installs it in a subfolder of the local package Cellar and symlinks the dita command to /usr/local/bin/dita.

To ensure the formula is kept up-to-date with each DITA-OT release, the core team of @dita-ot/developers should consider updating the formula as part of the release process.

Opening this issue to capture discussion and suggestions, including:

• how to best maintain this formula
• any changes we’d like to make to ensure the formula works like the default distribution package
• how to best promote the new installation option

1. Should the formula retain startcmd.sh in case users rely on it?

IMO no.

1. Should the formula set the $DITA_HOME environment variable?

We if you use dita CLI, you don’t need to override DITA_HOME. So IMO no.

• Although other Windows batch files are removed, config/env.bat currently remains and should also be excluded in the next version of the formula.
