Desktop, Mobile: Upgrade CodeMirror packages

[personalizedrefrigerator]

Summary

This pull request updates several @codemirror/ and @lezer/ packages. These packages aren't auto-updated by the Renovate bot because manual changes to yarn.lock are often required.

Testing plan

Web (Firefox on Windows 11):

1. Start Joplin
2. Open the note viewer.
3. Verify that headings and code blocks are highlighted.
   • Test note:

    This is a test!
    # Header
    
    ```javascript
    function foo() {
    	// Test
    	TEST();
    }
    ```
    <b>BOLD</b>
    <div>
    	TEST
    </div>

4. Install the "Extra Markdown Editor Settings" plugin and enable all non-advanced settings.
5. Verify that line numbers, a background grid pattern, and highlighted spaces are all present.
