Custom Connections premium link only works if already on premium

[seanwarmanshine]

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

• Version 9.3.0

Is your feature request related to a problem? Please describe.
Xero are introducing new subscription levels ("Ignite", "Grow", "Comprehensive" etc). I'm having trouble finding anywhere that tells me which of these levels allows the API to use OAuth.2.0's client_credentials for custom connections. Currently the docs just says "premium" accounts can use custom connections (which links to a page you can only see if you already have a premium account).

Describe the solution you'd like
I like to see some detail on which subscriptions allow for custom connections in the Custom Connections section of the README. Could be a link that goes to a relevant page in Xero's API docs, this one for example.

This is not SDK-related.

Custom connections are available for all plans in the UK, AU and NZ but you need to take out a custom connection subscription in addition to your Xero plan subscription.

It's related to the SDK's documentation. Let me better explain the issue:

If you visit this link (which is the one in the README) it responds with "Not Authorized" unless you already have a custom connection subscription.

It's not very likely you'd click that link if you already had a custom connection subscription.

My suggestion is to replace the link with one to Xero's custom connections documentation.
