Aligns with teams.ts PR #381 to update the AttachmentLayout enum values.

Changes

• Enum value: AttachmentLayout.CAROUSEL → AttachmentLayout.GRID (value: "carousel" → "grid")
• Docstring: Updated method documentation to reflect the new enum value

Usage

from microsoft.teams.api.models import AttachmentLayout, MessagingExtensionResult

result = MessagingExtensionResult(
    attachment_layout=AttachmentLayout.GRID,  # Previously CAROUSEL

can you change AttachmentLayout to be list | grid instead of list | carousel. Link microsoft/teams.ts#381 in the PR description.
