Spaces in folder name breaks iOS build

Description

Noticed this change while investigating #54140, but having a space in your folder name still results in a broken build (at least with the default XCode build phases).

A fix that seems to work for me is changing the "Bundle React code" build phase to include extra quotes to double wrap the file paths like so:

set -e

WITH_ENVIRONMENT="\"$REACT_NATIVE_PATH/scripts/xcode/with-environment.sh\""
REACT_NATIVE_XCODE="\"$REACT_NATIVE_PATH/scripts/react-native-xcode.sh\""

/bin/sh -c "$WITH_ENVIRONMENT $REACT_NATIVE_XCODE"

Steps to reproduce

1. Clone the repo, yarn, pod install.
2. Change the directory name to one with spaces (e.g. mv repo "space bug")
3. Optionally add set -x to the "Bundle React Native code and images" build phase to view the shell commands executed.
4. Attempt to build the xcode workspace.

Comece com a fase de build Bundle React code and images e com os pontos de entrada scripts/xcode/with-environment.sh e scripts/react-native-xcode.sh mostrados nos logs. Reproduza o build depois de mover o repositório para um caminho que contenha espaços e, em seguida, verifique se o workspace do Xcode é compilado com sucesso a partir desse caminho.
