Compatibility issue with upcoming release of Docsify v5 using Marked 13.x

[paulhibbitts]

Describe the bug
With the upcoming v5 release of Docsify, the Marked library has been updated to v13.x and this appears to cause this Plugin to no longer work as expected. docsifyjs/docsify#2467

To Reproduce
Steps to reproduce the behavior:

1. Go to https://paulhibbitts.github.io/docsify-v5-katex (a fork of your project using a recent Docsify v5 Preview)
2. View console for errors

Expected behavior
Display of included demo pages, etc.

Screenshots
n/a

Desktop (please complete the following information):

• OS: Mac
• Browser version Chrome 126.0.6478.183
• docsify version v5
• docsify-katex version v2

Additional context
Thank you for your awesome Katex plugin! I have used it in several open education starter kits and my open source app https://docsify-this.net. While Docsify v5 is still in development it is getting closer to release so I thought you would want an early notice of possible compatibility issues with Marked 13.x now being part of the build.

If I can be of any help with testing etc. please let me know. Thanks very much, Paul.
