fix: remove Liquid template curly braces from traceName description to avoid Fern SDK generation issues

The {{ }} syntax in OpenAPI descriptions causes Fern's Go SDK generator to
interpret them as template syntax, breaking code generation. Removed all
curly brace syntax from the traceName description.

Note: preview-go and preview-python CI failures are pre-existing on main
(confirmed by PR #928 having identical failures). This commit ensures our
change doesn't add to the problem.
