[BUG][Workspace]Incorrect Error Message for Workspace Description Field When Workspace Name is Invalid

[wanglam]

Describe the bug

When creating or editing a workspace with an invalid name, the workspace description field incorrectly displays an error message, even though the description itself is valid.

To Reproduce
Steps to reproduce the behavior:
1.Go to the workspace creation page or an existing workspace's edit page.
2.Enter an invalid workspace name (e.g., "Observability~!@").
3. Click the "Create workspace" in workspace create or "Save changes" in workspace detail
4.See an error message displayed for the description field, despite the description being valid.

Expected behavior
The expected behavior is that the workspace name field should display an error message for an invalid name, but the workspace description field should not show any error if the description itself is valid.
