### Problem Description

When viewing the API docs, specifically the page [webFrame](https://www.electronjs.org/docs/latest/api/web-frame), the item [webFrame.insertCSS](https://www.electronjs.org/docs/latest/api/web-frame#webframeinsertcsscss-options) has the wrong heading level.

### Proposed Solution

Remove the extra '#' character from the relevant markdown file.

### Alternatives Considered

None. There is only one way to improve this.

### Additional Information

Fixing this is also beneficial for users with screen readers, as they heavily rely on headings to know where on the page they are.
