Some users can not be mentioned to be tagged in conversations

Affected module
UI

Describe the bug
I'm trying to mention a user as part of the conversation on the description of a table and the user is not found in the proposed dropdown, even though i'm sure it exists. The user is "data-enablement". @aniketkatkar97 mentioned that there seems to be an issue with the suggestion popup with names containing -in them.

To Reproduce

Expected behavior
I would expect:

1. User to appear in the popup suggestion
2. The user is properly tagged (I see the name automatically in blue and underlined)

Version:

• OS: [e.g. iOS]
• Python version:
• OpenMetadata version: v1.3.1
• OpenMetadata Ingestion package version: [e.g. openmetadata-ingestion[docker]==XYZ]

Additional context
Add any other context about the problem here.

Seems like the same issue where we have a PR to fix the user search with special chars. @karanh37
