CreateAuthorizeUrl Method Not Found

[SimonEvans482]

SDK you're using (please complete the following information):

• Version: Xero.NetStandard.OAuth2 - 9.2.0.
  Xero.NetStandard.OAuth2Client - 1.6.0
  IdentityModel - 7.0.0

Describe the bug
When attempting to authorise via Pkce, I am getting an exception on client.BuildLoginUriPkce(codeverifier), in:

    Public Function GetLoginURI() As String
        codeverifier = GetRandomString()
        Return client.BuildLoginUriPkce(codeverifier)
    End Function

Exception Text:

System.MissingMethodException: 'Method not found: 'System.String IdentityModel.Client.RequestUrlExtensions.CreateAuthorizeUrl(IdentityModel.Client.RequestUrl, System.String, System.String, System.String, System.String, System.String, System.String, System.String, System.String, System.String, System.String, System.String, System.String, System.String, System.Nullable1, System.String, System.String, IdentityModel.Client.Parameters)'.'`

To Reproduce
Steps to reproduce the behavior:

1. Initiate an instance of XeroClient with XeroConfiguration
2. generate a codeverifier string
3. call client.BuildLoginUriPkce(codeverifier)

Expected behavior
Pkce auth flow to run without exception

Screenshots
I don't think necessary

Additional context
Have been using the SDK for a number of years without issue. May have recently updated NuGet package to latest version. This may be a reoccurrence of ticket #384

downgrading IdentityModel to 6.2.0 does resolve the issue, so presume version 7.0.0 support just needs to be added...

This is the same as issue: #554
