Describe the bug Mdx title contain comma will cause 404

To Reproduce Steps to reproduce the behavior:

just add some comma in Mdx file title, like this:

---

...some contents.

between in 'v1' and 'v2', and will see this page 404.

Expected behavior correctly display, not 404

Screenshots

System Info (if dev / build issue):

• OS: [e.g. iOS]
• Node version (please ensure you are using 18+)
• Npm version

Browser Info (if display / formatting issue):

• Version v2.1.0

Additional context I add console.log in /app/blog/[...slug]/page.tsx function Page()

sortedCoreContents.forEach((b)=>{
    if (b.slug.includes('sushi')){
    console.log(b.slug)
    console.log(b.filePath)}
  })

you'll see the same slug print twice. but i not familiar with js/ts.

I use / instead of , to avoid this.
