Comments field isn't reflect in Component Reference documentation

### The documentation URL

https://jmeter.apache.org/usermanual/component_reference.html

### Feedback

Every JMeter element has Comment parameter, but it isn't reflect in Component Reference documentation, only "Bolt Connection Configuration" has Comments parameter described as "Free text for additional details." with Required: No

I suggest move the Comments parameter definition to Introduction section

* Also Name parameter definition can be moved to Introduction section only
