list-roles-with-permission.sh seems to list each role several times

[Ftagn92]

Hello
list-roles-with-permission.sh script seems to duplicate each role, searching for a permission

`./list-roles-with-permission.sh bigquery.jobs.list
roles/automlrecommendations.serviceAgent
roles/bigquery.admin
roles/bigquery.admin
roles/bigquery.admin
roles/bigquery.resourceAdmin
roles/bigquery.resourceAdmin
roles/bigquery.resourceAdmin
roles/bigquery.resourceEditor
roles/bigquery.resourceEditor
roles/bigquery.resourceEditor

[...]
`
If this works as expected (i.e. if the list adds a line for GA/alpha/beta), is it possible to add this information next to the role name (alpha/beta/GA)?

Thanks for your work
