fix(template): eliminate the error that occurs when enabling eslint-plugin-markdown

[liby]

Description

The following code generated by Vite will encounter an error when the project is enabled with https://github.com/eslint/eslint-plugin-markdown.

Additional context

It doesn't seem necessary to introduce https://github.com/eslint/eslint-plugin-markdown for the Vite project. I have checked other code generated by Vite and haven't found other similar issues so far.
