json iterator version issue

[ashutosh100ms]

while running the xk6 load test with test.js on Loki server, it is throwing "go segmentation" error. Which is due to the JSON iterator version.
Right now the JSON iterator version, in go.mod file, is 1.1.10 which is not working as expected.
We have to use 1.1.12 as JSON iterator version.

I have tried to raise a PR for that but for me, it is giving "fatal: unable to access 'https://github.com/grafana/xk6-loki/': The requested URL returned error: 403".
