GitHub integration missing callback URL

[aldy505]

${url-prefix}/extensions/github/setup/ should also be included as one of callback URL, otherwise the app will fail. Specifying only the ${url-prefix}/auth/sso/ would fail the installation.

👇🏻 This works

Code in question:

Lines 20 to 26 in 3402f82

	| Setting | Value |
	| ------------------------------- | ------------------------------------------ |
	| Homepage URL | `${url-prefix}` |
	| User authorization callback URL | `${url-prefix}/auth/sso/` |
	| Setup URL (optional) | `${url-prefix}/extensions/github/setup/` |
	| Webhook URL | `${url-prefix}/extensions/github/webhook/` |
	| Webhook secret | "my-super-secret-example-secret" |
