[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).

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

- **Deploy 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-btp-kyma-environment%2Ftree%2Fmain%2Fexamples%2Fkyma-on-btp-reuse-sa).

- **Deploy Kyma runtime into 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-btp-kyma-environment%2Ftree%2Fmain%2Fexamples%2Fkyma-on-btp-new-sa).

Please remove the 3rd bullet point

If the development team has administrative access at the global account level, then the custom Identity Authentication tenant could be trusted at the global account level...
