I added a test for this too.

It "Should find version range for Az dependencies" {
    # Target known version to know the output from the API won't change
    $res = Find-PSResource -Repository 'MAR' -Name 'Az' -Version '14.4.0'
    
    # Version defined by "ModuleVersion"
    $res.Dependencies.Where{$_.'Name' -eq 'Az.Accounts'}.'VersionRange'.ToString() | Should -Be '[5.3.0, )'
    
    # Version defined by "RequiredVersion"
    $res.Dependencies.Where{$_.'Name' -eq 'Az.Resources'}.'VersionRange'.ToString() | Should -Not -Be '[8.1.0, 8.1.0]'
}

Looks good over all, just a test failure with 'Should find version range for Az dependencies'

 Expected '[8.1.0, 8.1.0]' to be different from the actual value, but got the same value.
  321:         $res.Dependencies.Where{$_.'Name' -eq 'Az.Resources'}.'VersionRange'.ToString() | Should -Not -Be '[8.1.0, 8.1.0]'
