run_cmd fail with options as first arg

[darwin67]

Summary

When using run_cmd with options like

run_cmd("--terragrunt-global-cache", "--terragrunt-quiet", "${get_terragrunt_dir()}/date_to_unix_ms", "2030-02-21")

following the docs

Running terragrunt-atlantis-config generate will fail with the following error

ERRO[0000]    9:   range_end   = run_cmd("--terragrunt-global-cache", "--terragrunt-quiet", "${get_terragrunt_dir()}/date_to_unix_ms", "2030-02-21")
ERRO[0000]
ERRO[0000] Call to function "run_cmd" failed: exec: "--terragrunt-global-cache": executable file not found in $PATH.

Running with the options works fine when working with terragrunt, but only fails when running terragrunt-atlantis-config.

Removing the options will pass but can potentially generate a lot of stdout noise when running run-all plan.

Expected behavior

Should not error.
