CLI Flag 'false' value
Boolean flags can only take arguments via --flag=[true|false] or for short names
(if available) -f=[true|false]. You cannot use --flag [true|false] nor can you
use the shorthand -f [true|false] as it will result in the following error:
Error: accepts 1 arg(s), received 2
Example:
# disable reading .terraform.lock.hcl
$ terraform-docs markdown --lockfile=false /path/to/module
