Bug: Broken URLs in Documentation (Incorrect `.mdx` or `.md` extensions)

[seifsapagh]

Describe the bug

several documentation links refer to files with incorrect extensions (.mdx vs .md), resulting in 404 errors.
this affects links to the Code of Conduct, Contribution Guide, and other pages.
I'd be happy to open a PR to fix these links.

My approach would be to update the links inside the .mdx files located in:
https://github.com/live-codes/livecodes/tree/develop/docs/docs

Example:
To fix the broken links on https://livecodes.io/docs/contribution,
I will update the broken references in contribution.mdx
and i will follow the same pattern for the other links mentioned below.

Looking forward to your feedback before I proceed. Thanks!

Steps to reproduce

These are the broken links I’ve found so far.

1. go to https://livecodes.io/docs/contribution
   1.1 click code of conduct (broken)
   1.2 click contribution guide (broken)

2. go to https://livecodes.io/
   2.1 click UI language button
   2.2 click help us Translate (broken)

3. go to https://livecodes.io/docs/license
   3.1 click listed here (broken).

Thank you @seifsapagh

These occured while upgrading docusaurus which moved to using mdx files instead of md. I must have missed these.

You are very welcome to start a PR. Please go ahead.

You can find the "help us translate" link here.

Thank you :)
