Hedge reads is known to have race conditions that causes hedged_reads.js to fail (SERVER-65329). We tried increasing timeouts but the test still fails on windows variants. We should disable hedged_reads.js from windows builds for the following reasons:

• SPM-3750 will remove the hedged reads feature and it's been deprecated in v8.0 already. We should avoid spending too much time investing in a fix for this.
• windows testing is expected to be deprecated.
