Sandboxed git+ dependency is not added correctly

[armstrys]

Describe the bug

When I am editing a sandboxed environment and add a dependency via the UI with git+https://github.com/xxxxxx/xxxx.git

The dependency is not added correctly.

When I run

uv add --script marimo_notebook.py git+https://github.com/xxxxxx/xxxx.git the dependency is added to the script correctly.

In the first case this section is omitted at the bottom of the dependencies.

# [tool.uv.sources]
# xxxx = { git = "https://github.com/xxxxxx/xxxx.git" }
