Refine .xcworkspace ignores for CocoaPods

[GetToSet]

Reasons for making this change:

I recently migrated a CocoaPods based project into a Swift Package Manager project and found issues when building the project with CI due to Project.xcodeproj/project.xcworkspace/ accidentally ignored by CocoaPods related rules. This PR fixes the issue.
