fix: Allow ROOT as a Repository Creation Template prefix

[bodgit]

Description

This fixes the aws_ecr_repository_creation_template resource and data source so they accept ROOT as a valid value. I think this was missed as I originally copied the validator from the pull-through cache code without adding this additional special case.

Tests added, explicitly not using ParallelTest so the resource and data source tests don’t fight over the one template that can exist.
