new build backend - scripts data: script not executable in wheel

[davidszotten]

Hi,

excited to try out the new build backend and happened to be looking at scripts data:

$ cat pyproject.toml

[project]
name = "test-uv-build-backend"
version = "0.1.0"
description = "Add your description here"
readme = "README.md"
requires-python = ">=3.12"
dependencies = []

[build-system]
requires = ["uv>=0.5,<0.6"]
build-backend = "uv"

[tool.uv.build-backend.data]
scripts = "scripts"

$ cat scripts/my-bin
#!/usr/bin/env bash

echo foo

$ ls -al scripts/my-bin
-rwxr-xr-x  1 david  staff  30 17 Dec 11:00 scripts/my-bin
   ^
