Title: [Feature] Hope to support percentage tasks

**Is your need related to a problem? Please describe what problem you encountered. **
At present, it seems that there is no function to support the completion of the progress for non-repetitive tasks

Describe your solution
I hope to add a percentage function to a single task. The task interface displays the current percentage. Click on the task to choose how much percentage to increase. The task will be automatically completed when it reaches 100%.

Describe options
Please clearly describe whether you have other options

extra information

目前计数事项（设置为目标值100）可以实现类似的功能，也有进度条展示。

后续可能也会推出更直观的百分比事项（但实际跟计数好像类似）。

The current count items (set to the target value of 100) can achieve similar functions, and there is also a progress bar display.

A more intuitive percentage item may be introduced in the future (but the actual count seems to be similar).
