Swiftgen plugin doesn't work with Xcode15 projects

[Oleg-E-Bakharev]

In Xcode15 it is possible to run build plugin as project build phase. Using plugin instead of standalone swiftgen simplifies setup of CI/CD.

But swiftgen plugin 6.6.2 doesn't work as build phase
It outs in build log:
Plugin doesn't support Xcode projects (it doesn't use the XcodeProjectPlugin library)

Please add support to build Xcode projects
