Remove Markdown hint from channel input footer

[2witstudios]

Summary

Removed the "Markdown supported" hint text from the channel input footer component.

Changes

• Removed the markdown hint span element that displayed "Markdown supported" text in the channel input footer
• This text was only visible on small screens and above (hidden on mobile via hidden sm:inline)

Rationale

The markdown hint appears to be redundant or no longer needed in the UI. This simplifies the footer layout and reduces visual clutter in the input area.
