[sitecore-jss] Use ['Retry-After'] header value without rounding off

CHANGELOG.md

@@ -31,7 +31,7 @@ Our versioning strategy is as follows:
     * Handle additional string error codes like ECONNRESET, ETIMEDOUT, EPROTO. Can configure more using DefaultRetryStrategy.
     * Retries has now been enabled by default with a default value of 3. It can be disabled by configuring it to 0.
     * [Retry-After] header now falls back to the default delay time when it comes out to be empty.
