[BUG]Timing trigger exception.

## Description
Triggering the workflow every second via Cron or Timer can lead to repetitive workflow triggering and confusing timing.

## Steps to Reproduce
CRON(0/1 * * * * ?)->A time-consuming custom activity

## Expected Behavior
Triggered once per second according to the expression or after the first real column workflow has completed execution, then triggered the second workflow.

## Actual Behavior
A second or even more workflows are triggered during the execution of the first workflow instance

## Screenshots

## Environment
- **Elsa Package Version**: 3.2.0-rc4
- **Operating System**: Windows 10
- **Browser and Version**: Edge 127.0.2651.95

## Log Output
No error logging output

## Troubleshooting Attempts
When the execution time of a custom activity (which is a time-consuming activity) is controlled within the trigger interval or the trigger time is set beyond the activity execution time, the abnormal workflow real column will be greatly reduced or even no.
