Minimum PowerShell Version?

The requirements for this module indicate a minimum PowerShell version of 5.1. However, in a 5.1 environment, when running `Get-FolioRecordsByQuery` I get the error:

```
Get-Date : A parameter cannot be found that matches parameter name 'AsUTC'.
At \Modules\FolioClient\0.0.3\FolioClient.psm1:165 char:24
+ if (((Get-Date -AsUTC) -ge $this.TokenExpiry) -or ($force)) {
+ ~~~~~~
+ CategoryInfo : InvalidArgument: (:) [Get-Date], ParameterBindingException
+ FullyQualifiedErrorId : NamedParameterNotFound,Microsoft.PowerShell.Commands.GetDateCommand
```

It appears that the -AsUTC parameter didn't exist until version 7.4: https://learn.microsoft.com/en-us/dotnet/api/microsoft.powershell.commands.getdatecommand.asutc?view=powershellsdk-7.6.0

Start in FolioClient.psm1 around line 165, where Get-FolioRecordsByQuery reaches the Get-Date -AsUTC call, and verify the behavior in a PowerShell 5.1 environment. Check how the module documents its minimum version and determine whether the compatibility requirement or the date handling needs to be corrected. Done means the stated support level matches the module's behavior and the command no longer produces this reported error.
