fix: include credentials when cookie across subdomains

[ghassanmas]

This URL of fetching guest_token is always LMS_ROOT_URL, however
in case multisite is being used the guest could be in a different
url. This change ensure that cookie is being sent if the other
site is a subdomain or shares parent domain with LMS_URL_ROOT

This might be realted to openedx/tutor-contrib-aspects/issues/925

Thanks for your contribution! Can you bump the version?

[ghassanmas]

@Ian2012 I just did, thanks for quick review :)

I was testing it locally however I'm getting cors error. Can you provide testing instructions?

I did:

• Create site configuration for demo.local.edly.io:8000.
• Open the instructor dashboard from that domain.
• Load Aspects:

The principle is ok, but I haven't been able to test that it actually works. If somebody can confirm this does the trick, I would support merging it.

@ghassanmas Maybe you should include the site configuration changes you were proposing in this comment openedx/tutor-contrib-aspects#925 (comment). However, if you are going to do that, then you can drop the current changes as those will not be needed anymore.
