Successfully built pocketbase_bin-0.22.17.tar.gz

I am distributing packages without python source files in a repository pip-binary-factory.

I discovered this while distributing the pocketbase-bin package: https://github.com/Bing-su/pip-binary-factory/tree/main/pocketbase

For now, I've fixed the issue by adding the file to the excludes, but you can reproduce the issue by fixing that part.

[tool.pdm.build]
is-purelib = false
source-includes = ["go.mod", "go.sum", "*.go", "download.nu"]
excludes = ["bin/*", ".gitignore", "pdm_build.py", "build_wheel.py"]

[tool.pdm.build]
is-purelib = false
source-includes = ["go.mod", "go.sum", "*.go", "download.nu"]
excludes = ["bin/*", ".gitignore"]

Refer to this source code and the produced files.

Thank you.
