403 forbidden in some region like Iran

From some regions in middle east like Iran we get 403 forbidden error, and as we found in shorebird docs: https://docs.shorebird.dev/faq/#can-i-use-shorebird-in-my-country, shorebird are available in all regions, but it's not available in Iran.
also the shorebird console and cli not available for developers and they faced same problem 403 forbidden.

we added some doc for this problem
shorebird.pdf

to reproduce this problem, you might find and use VPN with Iran IP and check the result.

we guess the problem is because of google cloud services are not available in all regions, so shorebird can't reach to that regions.

this is what clients get while shorebird trying to connect servers and check for available update patch:
