'Microsoft.Automation/automationAccounts/powershell7Modules/*' does not match any of the actions supported by the providers

Following documentation like: https://github.com/Azure/azure-powershell/issues/16399 to upload PowerShell 7 modules to Azure Automation Account results in errors like below when using a service principal with a custom role to achieve POLP:

```
{"error":{"code":"AuthorizationFailed","message":"The client '3c37*REDACTED*cde5' with object id '3c37*REDACTED*cde5' does not have authorization to perform action 'Microsoft.Automation/automationAccounts/powershell7Modules/write' over scope '/subscriptions/*REDACTED*/resourceGroups/ukasttdevrgr46b32e005/providers/Microsoft.Automation/automationAccounts/*REDACTED* /powershell7Modules/SpeechTranscriptionRecordingMover' or the scope is
invalid. If access was recently granted, please refresh your credentials."}}
```

Attempting to add `Microsoft.Automation/automationAccounts/powershell7Modules/write` to the custom role via the portal (`Microsoft.Authorization/roleDefinitions` API Version `2022-05-01-preview`) results in the error: `Validation error: Invalid action is present in "actions" : Microsoft.Automation/automationAccounts/powershell7Modules/write.` Adding `Microsoft.Automation/automationAccounts/powershell7Modules/*` gets passed the initial validation but then fails when updating the role with the error: `Microsoft.Automation/automationAccounts/powershell7Modules/*' does not match any of the actions supported by the providers.`

https://management.azure.com/providers/Microsoft.Authorization/providerOperations?api-version=2018-01-01-preview&$expand=resourceTypes doesn't return any operation types with powershell7modules in their name.

The workaround is to allow `Microsoft.Automation/automationAccounts/*` in the custom role, but this seems like we're exposing too many permissions to achieve this.

Start with the Azure providerOperations endpoint and the Microsoft.Authorization roleDefinitions API version 2022-05-01-preview described in the issue. Determine how the powershell7Modules write operation should be exposed for custom roles, and verify that a least-privilege role accepts the operation without requiring Microsoft.Automation/automationAccounts/*.
