Fix pypi-release.yml permissions

[VeckoTheGecko]

Description

The release workflow failed due to insufficient permissions (due to Zizmor hardening). I'll do a manual release.

  Error: Trusted publishing exchange failure: 
  OpenID Connect token retrieval failed: GitHub: missing or insufficient OIDC token permissions, the ACTIONS_ID_TOKEN_REQUEST_TOKEN environment variable was unset
  
  This generally indicates a workflow configuration error, such as insufficient
  permissions. Make sure that your workflow has `id-token: write` configured
  at the job level, e.g.:
  
  ```yaml
  permissions:
    id-token: write
  ```
