Subject: [PATCH] Export `UV_DEFAULT_INDEX` in `release.sh` (#27934)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Summary
--

Before this, running `./scripts/release.sh` produced this error on my
machine:

```console
❯ ./scripts/release.sh
Updating metadata with rooster...
warning: `VIRTUAL_ENV=/Users/brw/.virtualenvs/openai` does not match the project environment path `.venv` and will be ig
nored; use `--active` to target the active environment instead
error: The lockfile at `uv.lock` needs to be updated, but `--locked` was provided.

hint: To update the lockfile, run `uv lock`.
```

Passing an additional `--default-index` flag to the initial `uv run`
also works, but it seems easier
to export the environment variable for the whole workflow.
