Display block details on dynamic label hover

[radeksimko]

Currently we display just the value of the dynamic label, for example just spot_options name in this config:

resource "aws_ec2_fleet" "name" {
  dynamic "spot_options" {

  }
}

This is in contrast to hover data provided for the "native" block type

resource "aws_ec2_fleet" "name" {
  spot_options {
    
  }
}

We should display the equivalent amount of details about the block, such as block type, min/max items and the description (if available).
