I have seen information online that suggests it is part of the module "AzureAutomationAuthoringToolkit", but I don't understand how I install this into the environment the Function App runs in.stuff and am following a blog post below to try and get the auto-start up shut down working. I am fairly certain that I have followed this correctly. To me the error suggests that the environment doesn't have the module loaded.

I don't think you can use the command Get-AutomationPSCredential in the azure function, it is an Internal cmdlet belongs to the internal module Orchestrator.AssetManagement.Cmdlets, it is only available when you're executing runbooks in the Azure sandbox environment, or on a Windows Hybrid Runbook Worker.
So in your case, your option is to use the script in the automation powershell runbook, then use Invoke-WebRequest in the timer trigger to invoke the web request to the webhook URL of the runbook to start the runbook(As the script should be ran every 5 mins said by author).
Invoke-WebRequest -Uri <Webhook URI> -Method Post
For more details, you could refer to the link mentioned in the Github repo.
