No explicit block is causing errors

[gusfune]

After the release of 0.40.3 I have noticed that the runners were not triggering when having no block_device_mapping set in the terraform file.

The error show in AWS was:

ErrorMessage: 'Invalid device name /dev/xvd'

After some digging the issue found was that this block:

default = [{
    device_name           = "/dev/xvd"
    delete_on_termination = true
    volume_type           = "gp3"
    volume_size           = 30
    encrypted             = true
    iops                  = null
  }]

Actually should be

default = [{
    device_name           = "/dev/xvda"
    delete_on_termination = true
    volume_type           = "gp3"
    volume_size           = 30
    encrypted             = true
    iops                  = null
  }]

I managed to fix my main.tf file by setting this block below:

block_device_mappings = [{
    device_name           = "/dev/xvda"
    delete_on_termination = true
    volume_type           = "gp3"
    volume_size           = 30
    encrypted             = true
    iops                  = null
  }]
``

But, the default configuration should be reviewed. This was caused by #2014 to fix the issue I have reported on #1954.

Thx! Just find the same issue.

I have already pushed a fix for this @npalm on #2018 if that helps.

@gusfune thx, tested and one file was missed for the fix. Provided another fix on top of yours. Thanks for the help!
