Fix dependency.packageName evaluated by the terragrunt manager when the terraform source url contains double slashes and ssh as the protocol (e.g., git::ssh://git@mygit.com/hashicorp/example.git//subdir/test?ref=1.1.0 )

Changes

Changes behavior when evaluating dependencies with the terragrunt manager. Specifically, this changes the behavior with terraform sources that have double slashes in the URL path and ssh as the protocol

for example:

# terragrunt.hcl
terraform {
  source = "git::ssh://git@mygit.com/hashicorp/example.git//subdir/test?ref=v1.0.4"
}

• Closes Terragrunt: Failed to properly parse git/ssh dependency with sub directory #33772
• Failed to properly parse terraform dependency in terragrunt.hcl #33370
