ci: Fix Windows wheel creation (#2511)

## Why?

* Wheels were not created on Windows because it does not use bash by
default
* Once that works, downloading them will fail because
`actions/download-artifact` requires the `run-id` to access artifacts
from different workflows.

## What does this PR do?

* Add `actions: read` permission to release workflow.
* Configure `download-artifact` action to use `run-id` and `pattern` for
downloading wheels from a previous workflow run.
* Enable `merge-multiple` for downloading artifacts.
* Add `shell: bash` to build step in native release workflow.
