Add getRunDatesUntil method for generating multiple run dates until a specified end date

[le-pepe]

Summary

A new getRunDatesUntil method is added to generate execution dates based on a cron expression, limited by a specified end date. The method also allows setting a maximum number of iterations, including the current date, and handling time zones for date calculations.

Details

• The new method accepts an end date ($until), a maximum number of occurrences ($limit), and a reference time ($currentTime) to calculate the execution dates.
• It includes an option to include or exclude the current date in the results ($allowCurrentDate).
• The method uses the determineTimeZone function to manage time zones, which can either be specified or dynamically determined from $currentTime.
• If the $limit parameter is set to 0, the method defaults to $this->maxIterationCount.

Behavior

• The method returns an array of DateTimeInterface objects representing the calculated execution dates.
• If the end date is reached or the iteration limit is met, the process stops, and no further dates are added.

Tests

• Tests have been added to verify the correct generation of run dates, both with allowCurrentDate enabled and disabled.
• It has also been validated that the date limit and the end date are correctly respected.
