fix: normalize ContributeFooter route before GitHub link

[tansawit]

Summary

Fixes ContributeFooter.tsx URL generation to handle trailing slashes in window.location.pathname.

Problem

Routes like /intro/introduction/ were being transformed into intro/introduction/.mdx, producing invalid GitHub links (for example .../intro/introduction/.mdx).

Change

• Normalize path from window.location.pathname by trimming leading and trailing /.
• Avoid generating a path for / home route.
• Result is correct: /intro/introduction/ -> intro/introduction.mdx.

Validation

• Manual path normalization check via quick Node verification for common routes.

Hey! Thanks for the effort you put into this.
Could you provide more details on how to reproduce the bug? I tried reproducing it on my end but it seems to work all right, so I'm curious to know if I might be missing something.

• Were you on the .org or .dev site?
• Are there any pages that trigger it instead of others (like nested files e.g. https://frameworks.securityalliance.org/opsec/travel/overview on the .orgor https://frameworks.securityalliance.dev/devsecops/isolation/sandboxing-and-isolation on the .dev)
• Did you click on the ✏️ Contribute today! button or on the Suggest changes to this page one?
• Can you paste the github url it generates when clicking on the button and you encounter the issue?
• Any other info you might want to attach

Thanks again for the time and sorry you experienced issues in finding the pages on github 🙏🏻
