// "no-restricted-properties" rules are not properly merged when just using "extends".
// Therefore we have to have this file which calls a custom merge function.
// The merge function calls Object.assign with special handling for configuration such as
// `no-restricted-properties` and `no-restricted-syntax` which are array based - ensuring the two
// values being merged are concatenated
