fix(relocation): Working relocation page when organization is set to null (#63633)

I believe this [PR](https://github.com/getsentry/sentry/pull/63380)
broke the relocation page, since it is intended to be used when a user
does not have any organizations created, so no organization context.
This sets the `allowNull` option for `useOrganization`, so that the
feature component can be used for pages when an organization context is
not available.
