fix(docs): remove unsupported project-search format from span view

The <project>/<trace-id> format doesn't work because parseSlashSeparatedArg
treats a single-slash input as org/project (missing ID), not project/trace-id.
Unlike span list or trace view, span view can't fall back to two separate args
since the second positional is always a span ID.
