Add --remote_download_outputs=toplevel to xcodeproj.bazelrc

As titled. There's an issue when remote download minimal is generating empty app bundles when using Xcode.

error: Failed to read Info.plist of app /Users/ernesto/Library/Developer/Xcode/DerivedData/InstacartBazel-eqgbkfaxbhrobdfmvkzzkbbafnzs/Build/Products/Debug-iphonesimulator/bazel-out/ios_sim_arm64-dbg-ios-sim_arm64-min16.0-applebin_ios-ST-1de1fcec1e3b/bin/Instacart.app: The operation couldn't be completed. (SWBUtil.PropertyListConversionError error 1.) (in target 'InstacartDev' from project 'InstacartBazel')

Don't think we can set this globally yet as not every remote cache supports BwoB. We use all for example for local devs

Don't think we can set this globally yet as not every remote cache supports BwoB.

The default for Bazel is this, so I think we are safe re-enforcing the default? Then anyone that needs to override Bazel's default will need to do it for rules_xcodeproj as well? At this point remote caches really should support this, and it's more likely that someone wants this default than accidentally breaking their Xcode builds?

This is what I thought as well

Overriding (kinda forgot this was possible) and matching the defaults in Bazel make sense
