Not installed loki with tanka

[gespispace]

Describe the bug
If I try install loki by example in docs, install doesn't work.
Error in the docs
I think error in jsonnet-bundler. in this line, use only branch master, but in grafana/loki not have branch master.

To Reproduce
Steps to reproduce the behavior:

1. jb install github.com/grafana/loki/production/ksonnet/loki

Expected behavior
Install lib ksonnet loki

Environment:

• Infrastructure: Kubernetes
• Deployment tool: jsonnet

Screenshots, Promtail config, or terminal output

@gespispace Thanks for reporting!. It's indeed the problem with jb. Looks like it understands master branch by default whereas Loki uses main branch.

One workaround would be to use explicit main branch while installing loki and promtail

1. jb install github.com/grafana/loki/production/ksonnet/loki@main
2. jb install github.com/grafana/loki/production/ksonnet/promtail@main

We will update the doc soon!
