Invalid folder name for folder-iam. Module example using a folder name but it should be ID

[snahim-g]

TL;DR

Using a folder name for the folder-iam module errors out as the folder name is invalie.

Expected behavior

Adding iam roles

Observed behavior

Additional information

Honestly not sure why my folder name would be used here? Wouldn't GCP require a folder ID?

@snahim-g Thanks for the report. The folder resource "name" output from the folder resource actually has the id and is of form folders/{folder_id}. The module should accept both strings that are just ids or google_folder.iac_folder.name. Let me know if this works.

@bharathkkb We might want to consider changing the variable to folder_ids. Even though name is the technical definition, it's definitely confusing given the presence of display_name as well.

Changing this to FR.
