[release] 1.32.0 - Manually Sync Config Spec (#397)

### New Features
- New api `syncConfigSpecs` allows users to manually trigger the
synchronization of config specs in cases where the initial SDK
initialization has failed and you want to retry.

Return Type: `CompletableFuture<ConfigSyncDetails>`

Example usage: 
```

        CompletableFuture<ConfigSyncDetails> future = Statsig.syncConfigSpecs();
        ConfigSyncDetails configSyncDetails = future.get();
        configSyncDetails.getDuration();  
        configSyncDetails.getConfigSpecReady();  
        configSyncDetails.getFailureDetails();
        configSyncDetails.getLcut();  
```
