Bump go-spancheck

[jjti]

closes #4310

fix where I removed the embedding of the doc: jjti/go-spancheck@cd062ed

New doc:

	return &analysis.Analyzer{
		Name:  "spancheck",
		Doc:   "Checks for mistakes with OpenTelemetry/Census spans.",
		Flags: config.fs,
		Run:   run(config),
		Requires: []*analysis.Analyzer{
			ctrlflow.Analyzer,
			inspect.Analyzer,
		},
	}

There is no need to create a PR bumping minor version because dependabot handled updates. See this #4128 (comment) or this #3561 (comment)
