Description jumps to top on small window sizes on a tag's page

Summary

When viewing a specific tag's page (/-/tags/<tag>) on a small browser window or mobile device, the release description incorrectly jumps to the top of the page instead of remaining in its proper position below the release header.

The order of components in the mobile/small layout CSS is likely incorrect, causing the description to render before other elements.

This came up in a Zendesk Ticket - internal only

Steps to Reproduce

1. Navigate to a tag release page (e.g., /-/tags/<tag_name>)
2. Resize the browser window to below a certain width threshold (mobile/small layout)
3. Observe the position of the release description

Current Behavior

The release description appears at the top of the release section, above where it should be positioned.

Expected Behavior

The release description should remain in its correct position below the release header, regardless of the window size or device.
