/**
 * Once all changes have been done in the current branch, a new migration for all changes should be
 * created.
 *
 * In case a value should be migrated for a specific key, and in the same migration the key is
 * getting migrated, the key in the value migration is the "old" key (before the migration to the
 * new key).
 *
 * Migration order (function "applyMetadataMigrations"):
 * 1. app metadata key prefix
 * 2. app metadata values
 * 3. app metadata keys
 *
 * @example
 * // changes:
 * // commit: change key "X" to "Z"
 * // commit: change key "Y" to "A"
 * // commit: fix typo in reader setting "someTipo"
 * // commit: add metadata migration
 *
 * // result:
 * // old migrations:
 * // const migrations = [
 * //   {
 * //     keys: [{ oldKey: 'loadNextonEnding', newKey: 'loadNextOnEnding' }],
 * //   }
 * // ];
 *
 * // updated migrations
 * const migrations = [
 *   {
 *     keys: [{ oldKey: 'loadNextonEnding', newKey: 'loadNextOnEnding' }],
 *   },
 *   {
 *     keys: [
 *       { oldKey: 'X', newKey: 'Z' },
 *       { oldKey: 'Y', newKey: 'A' },
 *     ],
 *     // all stored values in the metadata (of this app) will get migrated
 *     values: [
 *       {
 *         oldValue: 'someTipo',
 *         newValue: 'someTypo'
 *       },
 *     ],
 *     // to migrate only the value of a specific key (in this case of "someKey"):
 *     // values: [
 *     //   {
 *     //     key: 'someKey',
 *     //     oldValue: 'someTipo',
 *     //     newValue: 'someTypo',
 *     //   },
