Mac M1, run jhbuild update, got "No such file or directory: 'xpra-gtk3.modules'"

[lpf6]

Describe the bug Run jhbuild update got error when I try to build from source on MacOS M1 Pro:

jhbuild update: failed to parse xpra-gtk3.modules: [Errno 2] No such file or directory: 'xpra-gtk3.modules'.

How can I aviod the error?

To Reproduce I follow the doc docs/Build/MacOS.md to install from source in Mac M1.

1. Setup gtk-osx And set PATH
2. Configure jhbuild to use our modules
3. when I run jhbuild update got error: "No such file or directory: 'xpra-gtk3.modules'".

System Information (please complete the following information):

• Mac OS 13.3.1 (a)
• Apple M1 Pro
• aarch64 Terminal

Additional context I has uninstall brew in my MAC to build source, their is all logs of jhbuild update when I run again:

I found where 'xpra-gtk3.modules', it is in another repo, I fix by:

git clone https://github.com/Xpra-org/gtk-osx-build.git
cd gtk-osx-build
jhbuild update

Maybe better to add this step to doc.
