Invalid VM resource name when adding resource to AZDO environment (RHEL 9)

When encountering the "Invalid VM resource name" error message when adding a resource in Azure DevOps (AZDO) for a Red Hat Enterprise Linux 9 (RHEL 9) environment, it's possible that the name of the resource you're trying to add contains invalid characters or is too long. In Azure DevOps, VM resource names must meet the following criteria: The name must start with a letter. The name can contain only letters, numbers, and the hyphen (-) character. The name must contain between 3 and 23 characters. If your resource name doesn't meet these criteria, you'll need to change it to a valid name before you can add it to your AZDO environment.
