 * Creates a {@link CronExpression} that repeats at approximately every N minutes.
 *
 * For values under 60, produces a cron expression using minute intervals (e.g., 5 produces every 5th minute).
 * For values of 60 or more, the expression is split into hours and minutes (e.g., 90 minutes becomes
 * every 1 hour at minute 30), which means intervals won't be exactly N minutes apart.
 *
 * @param inputMinutes - interval in minutes between executions
 * @returns a cron expression string that approximates the requested interval
 *
 * @example
 * ```ts
 * // For intervals under 60 minutes:
 * cronExpressionRepeatingEveryNMinutes(5);  // returns a cron for every 5th minute
 *
 * // For intervals of 60+ minutes:
 * cronExpressionRepeatingEveryNMinutes(90); // returns a cron for every 1 hour at minute 30
 * ```
