Preserve relative projectDirPath values when writing a loaded project.

If a PBX project contains a relative projectDirPath, the reader resolves it to an absolute sourceRoot. Line 89 then writes that absolute path into project.pbxproj. After the project moves to another checkout, Xcode continues to use the old path for SRCROOT. Preserve the relative value, or serialize a path relative to the bundle’s parent for loaded projects. A nonempty projectDirPath affects SRCROOT. (github.com)

Review comment at @Sources/XcodeProjects/XcodeProject.swift at line 89:
Update the projectDirPath serialization so loaded projects preserve the original
relative path, or write a path relative to the project bundle’s parent, instead
of serializing the resolved absolute sourceRoot path.
