[doc issue] Terraforming Kyma Runtimes - Access to SAP BTP in the Continuous Integration Scenario

[lechnerc77]

Issue description

The content of the section "Access to SAP BTP in the Continuous Integration Scenario" is a bit misleading as this has only partially something to do with the "Access" to the scenario.

I would propose to rename the section to "Supported sceanrios" and add as content

There are two main use cases that are supported by the Terraform module:

- The team wants to deploy the Kyma runtime in an existing subaccount. This requires that the technical user executing the Terraform script in the CI/CD pipeline is assigned the role collection "Subaccount Administrator" in the targeted subaccount. The module will create all required resources in the given subaccount. See an [example](https://help.sap.com/docs/link-disclaimer?site=https%3A%2F%2Fgithub.com%2Fkyma-project%2Fterraform-module%2Ftree%2Fmain%2Fexamples%2Fkyma-on-btp-reuse-sa).

- The team wants to deploy the Kyma runtime into a new subaccount. This requires that the technical user executing the Terraform script in the CI/CD pipeline is assigned the role collection "Global Account Administrator" in the targeted SAP BTP global account. The module will create all required resources including a new subaccount. See an [example](https://help.sap.com/docs/link-disclaimer?site=https%3A%2F%2Fgithub.com%2Fkyma-project%2Fterraform-module%2Ftree%2Fmain%2Fexamples%2Fkyma-on-btp-reuse-sa).
