[eas-cli] change url in fingerprint:compare

[quinlanj]

Why

I'm in the process of changing the fingerprint path to fingerprints in the website to be consistent with all our other routes here https://github.com/expo/universe/pull/18533

This PR updates the URL to match the desired endpoint path on the Expo website.

How

Updated the URL path construction in the FingerprintCompare command to use the correct plural form /fingerprints/ instead of /fingerprint/ when generating the comparison URL.

Test Plan

Ran fingerprint:compare
