Revert "lib/protoparser/opentelemetry/firehose: escape requestID before returning it to user (#6451)"
This reverts commit cd1aca217c.

Reason for revert: this commit has no sense, since the firehose response has application/json content-type,
so it must contain JSON-encoded timestamp and requestId fields according to https://docs.aws.amazon.com/firehose/latest/dev/httpdeliveryrequestresponse.html#responseformat .
HTML-escaping the requestId field may break the response, so the client couldn't correctly recognize the html-escaped requestId.
