Find breaks on dependency processing when using relative working dir

[pseudomorph]

Describe the bug

When running the find command with a relative --working-dir input, errors of the following sort occur:

Rel: can't make <X> relative to <Y>

Steps To Reproduce

Given the following structure:

deploy-1/terragrunt.hcl

terraform {
  source = "./"
}

include "foo" {
  path = "./foo.hcl"
}

deploy-2/terragrunt.hcl
terraform {
  source = "./"
}

include "foo" {
  path = "./foo.hcl"
}

dependency "dep1" {
  config_path = find_in_parent_folders("deploy-1")
}

❯ terragrunt find --working-dir ./deploy-2 --external --include --dependencies --json
10:00:03.949 ERROR  Rel: can't make ../deploy-1 relative to ./deploy-2
Rel: can't make ../deploy-1 relative to ./deploy-2
10:00:03.952 ERROR  Unable to determine underlying exit code, so Terragrunt will exit with error code 1

❯ terragrunt info print --working-dir deploy-2

}

❯ cd deploy-2

    }
  },
  {
    "type": "unit",
    "path": ".",
    "include": {
      "foo": "foo.hcl"
    },
    "dependencies": [
      "../deploy-1"
    ]
  }
]

❯ terragrunt info print

  "terraform_binary": "tofu",
  "terraform_command": "print",
  "working_dir": "/Users/rossstrickland/repos/external/terragrunt/deploy-2"
}

Expected behavior

find should produce consistent results between the two commands.
