terraform: run init with no-color, too (#5147)

* terraform: run `init` with no-color, too

When running `terraform init` fails, it would output ansi color sequences, making the output hard to read.

Maybe setting TF_IN_AUTOMATION would also be beneficial: https://www.terraform.io/cli/config/environment-variables#tf_in_automation

* add changelog fragment for `terraform init -no-color`

* move changelog into correct directory; add PR link
