feat(tutorials): Extend E2E Adopter Journey with a DTR and matching tutorials

### Description

The current E2E Adopter Journey covers the usage of the EDC within a local setup (MXD) and guides a reader from setting up the environment to successfully exchange data with a second EDC. To better represent the usage of data providers and consumer within CX, another toturial on exchanging DTs needs to be added.

This Epic is dedicated to structuring the tasks to add a DTR to the setup and provide further tutorials to cover the handling of DTs in CX.

### Issues

- [ ] https://github.com/eclipse-tractusx/eclipse-tractusx.github.io/issues/729
- [ ] Check the description of the DTR in the "Inform" section of the E2E Adopter Journey @jkbquabeck
- [x] Highlight DTR-tutorials-introduced components in the E2E Adoprt Journey architecture @jkbquabeck
- [ ] https://github.com/eclipse-tractusx/eclipse-tractusx.github.io/issues/732
- [ ] Add seed data for the DTs in the E2E Adopter Journey tutorial @tunacicek & @jkbquabeck

### Further info
- Decision taken to deploy all E2E components at once, including the DTR
- Decision taken to include all information on MXD-extending components and highlight those beyond the initial MXD deployment in the architecture. This serves as preparation for components and tutorials added in the furutre (e.g.) third EDC or portal).
- Tuturials shall be added sequentially, following the previously existing EDC tutorials
