PHP Extension 5.37.0 released

• Improvement: The “sample rate” settings have been renamed to “trace sample rate” to more clearly indicate that they only affect whether trace timeline information is collected rather than whether a request should be ignored entirely. The old names are still available for backwards compatibility. Going forward the INI tideways.trace_sample_rate, the environment variable TIDEWAYS_TRACE_SAMPLE_RATE, or the trace_sample_rate option when calling Profiler::start() should be used.
• Improvement: Individual PHPUnit test cases now create full spans.
