Hi, recently I've discovered that the floppy_content statement doesn't work at all when used in conjunction with any of the vmware builders (vmware-iso or vmware-vmx) provided by this plugin.

Overview of the Issue

As the packer vmware plugin documentation states, there are some statements to configure a floppy disk in the virtual machine that's built by packer. This floppy disk is really useful for unattended Windows installs.

However, when the floppy_content statement is used no floppy disk is created by packer neither attached to the virtual machine. Any of the other statements (floppy_files or floppy_dirs) work as expected.

Reproduction Steps

Create a packer template with floppy_content, packer will ignore that option and build the template without creating the corresponding floppy disk.

Plugin and Packer version

packer 1.8.1
packer-plugin-vmware 1.0.7

Simplified Packer Buildfile

The following packer template can be used to reproduce the issue:

packer {
  required_version = "~> 1.8.1"

  required_plugins {
    vmware = {
      source = "github.com/hashicorp/vmware"
      version = ">= 1.0.0"
    }
  }
}

locals {
  alpine_base_url = "http://dl-cdn.alpinelinux.org/alpine/v3.16"
  alpine_iso_url  = "${local.alpine_base_url}/releases/x86_64/alpine-virt-3.16.0-x86_64.iso"
  alpine_iso_checksum_url = "${local.alpine_iso_url}.sha256"
  alpine_repository_url = "http://dl-cdn.alpinelinux.org/alpine/v3.16/main"
}

source "vmware-iso" "alpine" {
  iso_checksum = "file:${local.alpine_iso_checksum_url}"
  iso_url      = local.alpine_iso_url

  communicator = "none"
  headless     = false

  floppy_content = {
    "hello.txt" = "Hello world!"
  }

  boot_command = [
    "<wait5>",
    "root<enter>",
    "<wait>",
    "mount -t vfat /dev/fd0 /media/floppy<enter>",
    "<wait>",
    "cat /media/floppy/hello.txt<enter>",
    "<wait10>",
  ]
  boot_wait = "10s"
}

build {
  sources = ["vmware-iso.alpine"]
}

As you can see, this template is pretty simple. An alpine ISO is downloaded and a floppy must be created with a hello.txt file, at boot time the floppy disk is mounted and the hello.txt file is printed to stdout.
