Bump Xcodeproj to 1.27.0

[andrewash]

The Fix

Bump Xcodeproj version requirements to allow version 1.27.0

The latest version of cocoapods, 1.16.2 now requires at minimum 1.27.0 of xcodeproj
See these release notes

This PR bumps Xcodeproj to restore compatibility between the latest versions of Kintsugi and Cocoapods.

I've verified that running bundle install within my project whose Gemfile depends on kintsugi now works. However I haven't tested the functionality of kintsugi for compatibility with xcodeproj 1.27.0 as I'm not sure what to test for.

I hope this is helpful, in any case.

The Bug

Before this PR, running bundle install within my project root results in this error

Fetching https://github.com/pbsupplyco/Kintsugi.git
Fetching gem metadata from https://rubygems.org/........
Resolving dependencies...
Could not find compatible versions

Because every version of kintsugi depends on xcodeproj >= 1.19.0, <= 1.25.0
  and cocoapods >= 1.16.2 depends on xcodeproj >= 1.27.0, < 2.0,
  every version of kintsugi is incompatible with cocoapods >= 1.16.2.
So, because Gemfile depends on cocoapods = 1.16.2
  and Gemfile depends on kintsugi >= 0,
  version solving has failed.

FYI before this fix, my Gemfile had

source 'https://rubygems.org'

ruby '~> 3.2.1'

gem 'activesupport', '= 7.0.8'
gem 'cocoapods', '= 1.16.2'
gem 'fastlane', '~> 2.225.0'
gem 'kintsugi', require: false

Once I updated kintsugi to run off the feature branch I'm merging in, it worked fine.
