/**
 * The `BearerAuthProvider` class is an implementation of {@link IHeadersProvider}
 * that uses a bearer token for authentication. This class is
 * responsible for providing the authentication headers to the SDK. Note that it does
 * not handle token expiration or renewal. The token must be set manually using the
 * `setToken` method. Nor does it handle token retrieval. The token must be provided
 * in the configuration object or set manually using the `setToken` method.
 *
 * This class is useful for scenarios where you have a static bearer token that
 * does not expire or where you want to manage the token lifecycle yourself.
 *
 * @example
 * ```typescript
 * const authProvider = new BearerAuthProvider({
 *   config: {
 *     CAMUNDA_OAUTH_TOKEN: 'your-bearer-token',
 *   },
 * })
 *
 * authProvider.setToken('newTokenValue')
 * ```
