don't use graphql cache for polling builds

[dsokal]

Checklist

• I've added an entry to CHANGELOG.md if necessary.

Why

This fixes an issue that I introduced in 279dfd0
Because of the default graphql cache policy the build status never gets updated when running eas build.

How

I set the cache policy to network-only for the BuildQuery.byIdAsync query

Test Plan

I ran a build and observed the build status transitions.
