/**
 * Handles OpenID Connect (OIDC) token retrieval and exchange for CI environments.
 *
 * This function is designed to work in Continuous Integration (CI) environments such as GitHub Actions
 * and GitLab. It retrieves an OIDC token from the CI environment, exchanges it for an npm token, and
 * sets the token in the provided configuration for authentication with the npm registry.
 *
 * This function is intended to never throw, as it mutates the state of the `opts` and `config` objects on success.
 * OIDC is always an optional feature, and the function should not throw if OIDC is not configured by the registry.
 *
 * @see https://github.com/watson/ci-info for CI environment detection.
 * @see https://docs.github.com/en/actions/deployment/security-hardening-your-deployments/about-security-hardening-with-openid-connect for GitHub Actions OIDC.
