EXPO: configuration of standard-version-expo for a code base that has multiple configuration files

.versionrc.js

/* What?
 *   A configuration for standard-version-expo that updates multiple config files
 *   by dynamically identifying them from a sub-directory when you bump the
 *   version using the `standard-version` tool
 *
 * How?
 *   Modelled from the post by @bycedric: https://dev.to/bycedric/simplify-expo-releases-with-standard-version-2f4o
 *   Follow the setup instructions listed at the URL above or at https://github.com/expo-community/standard-version-expo
 *
 * Why?
 *   My expo app code is being used to generate different flavours of the app per corporate client - which means, in fact,
 *   generating different apps per client.  To keep all of our clients' apps current, we force all app configs to update
 *   at the same time.
 *   Each client has their own configuration stored in <PROJECT_ROOT>/app-configs/<CLIENT_NAME>/app.config.js
 *   So this code is run by `standard-version` and dynamically identifies all of the `app.config.js` in the `app-configs`
 *   subdirectory.
