stop uploading packages to downloads.rapids.ai (#2688)

Contributes to rapidsai/build-planning#181

* removes all uploads of conda packages and wheels to `downloads.rapids.ai`

## Notes for Reviewers

### How I identified changes

Looked for uses of the relevant `gha-tools` tools, as well as documentation about `downloads.rapids.ai`, being on the NVIDIA VPN, using S3, etc. like this:

```shell
git grep -i -E 's3|upload|downloads\.rapids|vpn'
```

### How I tested this

See "How I tested this" on rapidsai/shared-workflows#364
