fix: check return code of ms graphapi /me request.

[floriankramer]

When using the microsoft oicd provider and tyring to link an account with insufficient scope (e.g. missing User.Read) for the authorization code the request to https://graph.microsoft.com/v1.0/me used to determine the user id fails silently. This request is used when building the Context to get the user id, which is used as a unique identifier for the credentials.

The result is that the identifier in the identity_crendential_identifiers table is microsoft:. As soon as a second user tries to link their account ory attempts to create a secondcredential identifier with the same identifier of microsoft:. The linking then fails, and the user logs in as the first user who linked with microsoft if they use microsoft oicd.

This pr adds a check to make sure the status code returned from the graph api is 200. There will be a separate pr from a colleague that updates the documentation to make it more clear which scopes are needed for microsoft oicd.

I haven't touched anything that should trigger the linter errors (and am getting very different errors locally in code that I've also not changed), so it seems like they are caused by upstream code.

The linter errors came from a premature update of the gofmt binary and our use of Open API. I updated the PR, with our state in master. Should be fixed now. :)
