[Feature][param] The built-in parameters cannot express the beginning date of the month for n-1 days

### Search before asking

- [X] I had searched in the [issues](https://github.com/apache/dolphinscheduler/issues?q=is%3Aissue) and found no similar feature requirement.

### Description

example:
Today is August 26, 2024
Yesterday: $[yyyy-MM-dd-1] = 2024-08-25
At the beginning of the month: ??? = 2024-08-25 --> 2024-08-01
Unable to obtain the beginning date of the month based on $[yyyy-MM-dd-1]

### Use case

I hope to express it through built-in parameters and pass the parameters through another task

Start by tracing DolphinScheduler's built-in parameter handling for date expressions such as $[yyyy-MM-dd-1]. Confirm how parameters are passed to another task, then define and test behavior that resolves the beginning of the current month, such as 2024-08-01 for August 26, 2024.
