fix: header must be a string, not array

The header must be a string, not an array. Per the got documentation, `headers` is of type `object<string, string>`. See https://github.com/sindresorhus/got/blob/v14.6.6/documentation/2-options.md#headers

Fixes the mis-typing problem introduced in #919 which appears to cause GitLab releases to fail with incorrect `EINVALIDGLTOKEN Invalid GitLab token.` errors
