Metrics for http_req_connecting http_req_duration and few more are not sent to Dynatrace

[kumardushyant]

Describe the bug
When using this extension, I see few metrics is generated as

k6.http_reqs,tls_version="tls1.2",status="404",name="https://petstore.swagger.io/v2/pet/9223372036854284000",expected_response="false",error_code="1404",url="https://petstore.swagger.io/v2/pet/9223372036854284000",scenario="scenario",proto="HTTP/2.0",method="GET",group="::Scenario: "scenario01"::Test:::The pet id:9223372036854284000 does not exist in the store"  1 1683259839240

This causes upload to Dynatrace fail with error

Expected behavior
Parse of K6 results should be able to get correct metrics to upload to Dynatrace

Desktop (please complete the following information):

• OS: Ubuntu (WSL2)
• K6 version = k6 v0.44.0 ((devel), go1.20.3, linux/amd64)
• xK6 Dynatrace version =

k6 v0.43.1 ((devel), go1.20.3, linux/amd64)
