[aws inventory] fix scanning all regions

[ericzinnikas]

getRegions function has no profile argument passed to it and fails as such:

$ ./lw_aws_inventory.sh -p Account123-RoleABC

"Profile", "Account ID", "Regions", "EC2 Instances", "EC2 vCPUs", "ECS Fargate Clusters", "ECS Fargate Running Containers/Tasks", "ECS Fargate CPU Units", "ECS Fargate License vCPUs", "Lambda Functions", "MB Lambda Memory", "Lambda License vCPUs", "Total vCPUSs"
Account123-RoleABC, 123456790,
You must specify a region. You can also configure your region by running "aws configure".
Regions: , 0, 0, 0, 0, 0, 0, 0, 0, 0, 0

After this change, it properly scans all regions:

$ ./lw_aws_inventory.sh -p Account123-RoleABC

"Profile", "Account ID", "Regions", "EC2 Instances", "EC2 vCPUs", "ECS Fargate Clusters", "ECS Fargate Running Containers/Tasks", "ECS Fargate CPU Units", "ECS Fargate License vCPUs", "Lambda Functions", "MB Lambda Memory", "Lambda License vCPUs", "Total vCPUSs"
