Steps to reproduce

Passing -RequiredModules directly to New-ModuleManifest works:

$ModuleA = New-Object -TypeName Microsoft.PowerShell.Commands.ModuleSpecification @{
    ModuleName = "MyModule"
    RequiredVersion = [semver]"0.1.2"
}

New-ModuleManifest -Path:"$PSScriptRoot/ModuleB.psd1" -RequiredModules:$ModuleA

Passing -RequiredModules to Update-ModuleManifest fails:

$ModuleA = New-Object -TypeName Microsoft.PowerShell.Commands.ModuleSpecification @{
    ModuleName = "MyModule"
    RequiredVersion = [semver]"0.1.2"
}

New-ModuleManifest -Path:"$PSScriptRoot/ModuleB.psd1"
Update-ModuleManifest -Path:"$PSScriptRoot/ModuleB.psd1" -RequiredModules:$ModuleA

A workaround is to ensure that ModuleA is installed, then Update-ModuleManifest won't fail.

Expected behavior

It's possible to set Required Module via Update-ModuleManifest

Actual behavior

It's not possible to set Required Module via Update-ModuleManifest, it errors with

Cannot update the manifest file 'D:\programming\pwsh/ModuleB.psd1' because the manifest is not valid. Verify that the manifest file is valid, and then try again.'The specified RequiredModules entry 'MyModule' in the module
     | manifest 'D:\programming\pwsh\PSGet_ModuleB.psd1' is invalid. Try again after updating this entry with valid values.'
