Desktop,Mobile: Resolves #10031: Upgrade CodeMirror 6 packages

[personalizedrefrigerator]

Summary

Upgrades CodeMirror 6 packages, resolving #10031.

Notes

This pull request does not update @codemirror/language-data -- doing so increases the mobile bundle size from 1.7 MB to 2.2 MB. Additionally, it seems to trigger Webpack's chuncking mechanism (though we can disable it with output.chunkFormat = false).

Testing

1. Create a new document with the following content:

# Test

>
> This is a block quote.
>

Should have link formatting:
[This is a link](https://joplinapp.org/). https://this.is.a.test.joplinapp.org/

Should auto-renumber:
1. This
2. is
    1. This
    2. is
    3. a
    4. test
5. a
6. list
7. testing...


`shouldnotspellcheck` Should spllchek.

```javascript
function foo() {
    // This should be highlighted.
}
```

# Test 2
## Test 3
### Test 4

```yaml
a:
    b:
    - c
    - d
```

| a | b | c|
|---|---|--|
|  |   |   |
|test| | |

2. Verify that links, code blocks, headings, and block quotes have the correct styling in the beta editor.
3. Verify that the table is in a monospaced font.
4. Verify that numbered list continuation works.
5. Select everything
   • Verify that "select all" works on iOS
6. Duplicate it
7. Repeat steps 5 and 6 three more times.
8. (Desktop only) Enable vim keyboard emulation
9. Jump to the top of the document (gg) then to the end (G)
10. Go to the middle of the numbered list
11. Open a new line (o)

This has been tested successfully on:

• Ubuntu 23.10
• Android 13
• iOS

Note: On iOS, the inline code region is spellchecked (despite having spellcheck="false"), but this doesn't seem to be a regression (comparing with latest beta).

#9675 seems to be fixed! (It may alternatively have been fixed by #10174).
