the bold text appears as **text** on the reading page

Bug Report:

Bug Description:
In a Chinese language environment, while using Outline self-hosted version 0.75.2, when a sentence includes text formatted in bold within the editor, this formatting does not carry over to the shared reading page. Instead, the bold text appears as **text** on the reading page.

To Reproduce:

1. Access the Outline self-hosted platform (version 0.75.2).
2. Create or edit an article containing a sentence with Chinese characters in bold format.
3. Save the changes and preview or share the article to view the read-only version.
4. Notice how the bold formatting is not preserved; it's displayed as **text**.

Expected Behavior:
When a user formats text as bold within the editor, this formatting should be consistently maintained across all views, including the shared reading page.

Desktop Environment Details:

• OS: macOS 14.2.1
• Browser: Chrome
• Version: 121.0.6167.184 (Official Build) (arm64)

I also encountered this problem. I fixed it in my own fork at shepherdwind@266ff7b. You can try the image I built at https://hub.docker.com/r/shepherdwind/outline. As for the markdown-it plugin, I will release a separate package.

The root cause of the issue is that markdown-it parses **==xxx==**xx-like processes abnormally. When a special character such as +-= or a Chinese semicolons here is encountered before the second **, it recognizes an unclosable tag, so two open ** are ultimately output directly. In edit mode, rendering follows a different process, so there are no issues on the editing page.
