Improve the documentation to explain how private Terraform provider can be init

[fdebuire]

Hello,

This doc is explaining how providers are loaded: https://docs.burrito.tf/user-guide/private-modules/

But I didn't find a doc that explain how to use a Terraform private registry (in our case JFrog).

It's probably as easy as this doc: https://docs.burrito.tf/user-guide/private-modules/#3-mount-those-configurations-files-in-the-runners-configuration (but for the files .terraform.d/credentials.tfrc.json and .terraformrc) but a small doc specific to burrito might help.

Hello,

Yes I think it can be done this way.

Beware to not enable Hermitcrab in Burrito's Helm chart (disabled by default) as it overrides the TF_CLI_CONFIG_FILE environment variable in the runner to use the Hermitcrab installation as a provider registry instead of the default one.

Contributions are welcome in the documentation if you manage to make Burrito works with a private provider registry 😄
