[bug]Empty text nodes are not allowed

[jerrycompal]

I encountered an error when reloading saved JSON data after using shift+enter to insert a line break in the text.

Error prompt: Empty text nodes are not allowed.

The input I entered was: Test Report 2023-05-30 (use shift+enter to line break after the date)
An additional {"type":"text","text":"","styles":{}} was included, which caused the JSON to fail to load.

Here is the JSON data I received:

[{"id":"b1250752-20c3-487b-b6ce-70fbbda51673","type":"heading","props":{"textColor":"default","backgroundColor":"blue","textAlignment":"center","level":"2"},"content":[{"type":"text","text":"Test Report","styles":{}},{"type":"text","text":"","styles":{}},{"type":"text","text":"2023-05-30","styles":{}}],"children":[]},{"id":"9d682c8e-d27f-4e26-ac8a-021d852b9969","type":"paragraph","props":{"textColor":"default","backgroundColor":"default","textAlignment":"left"},"content":[],"children":[]}]

// Add a '\n' in the text {"type":"text","text":"\n","styles":{}} , it works fine .
