Markdown files with several dots . in name are not routed

[ianis]

Describe the bug

A markdown file with several dots . such as software-1.2.3.md is not properly routed and leads to a 404 error.
I guess that the router assumes that there is a file named /software-1.2.3 with the .3 extension when using cleanUrls.

Reproduction

1. Create a new VitePress project
2. Create a new markdown file named software-1.2.3.md with some content.
3. Create links the /software-1.2.3 page in the index.md file.

[/software-1.2.3](/software-1.2.3)
[/software-1.2.3.md](/software-1.2.3.md)

5. Enable cleanUrls.
6. Click the links on the index page.

Expected behavior

The router should load the page /software-1.2.3 when cleanUrls are active.
