Generate spans containing attributes with array values (#19)

* Update to go 1.21.x

* Send content type and accept header for HTTP requests

This is useful to generate attributes with array values

* The template example now sends attributes with array values

* Use local rand.Rand instance instead of package global rand.Seed()

* Update dependencies
