## Is your feature request related to a problem? Please describe.
During debugging, when a newline character appears in the previewed string variable, it is very difficult to recognize the content

## Describe the solution you would like
When debugging code in VsCode and previewing the value of a string type variable, display the newline character (\r\n) as a newline instead of a newline character.

## Applicable Scenarios
It takes effect when previewing the value of a string variable in the debug state

## Describe alternatives you've considered
Display in the current format. Add a "View Details" button in the preview attempt. Click the button to display the string content and process the newline character as a newline
