Steps to reproduce

After Sydney's Trusted Package Management presentation during PSConfEU 2024 Minicon, I was curious to give it a try. Unfortunately, I'm stumbling on the following error message:

Install-PSResource: Repository 'mar' is not a known repository type that is supported. Please file an issue for support at https://github.com/PowerShell/PSResourceGet/issues

The steps to reproduce the issue:

1. Run the following command: Register-PSResourceRepository -Name mar -Uri 'https://mcr.microsoft.com' -Trusted
2. Install the module by running the following: Install-PSResource -Name Az.Accounts -Repository mar

The error message appears. Did I miss a step while registering or installing?

Expected behavior

Should install Az.Accounts module using MAR as repository.

Actual behavior

See description.
