test: Update Inline_editing_3_spec.js to include expected JSON parsing (#36721)

## Description
<ins>Root cause</ins>
This spec was failing because it was string comparing the values,
whereas the source was a JS Object. This sometimes caused spec to fail.

<ins>Solution</ins>
This pull request updates the `Inline_editing_3_spec.js` file to include
the expected JSON parsing. The changes ensure that the correct JSON
parsing is performed when editing a table cell and saving the changes.

Fixes #36720
_or_  
Fixes `Issue URL`
> [!WARNING]  
> _If no issue exists, please create an issue first, and check with the
