Routes inconsistent in whole repo

### Current Behavior

Routes are inconsistent.

See e.g.
- [Release Changelog R24.08](https://github.com/eclipse-tractusx/eclipse-tractusx.github.io/blob/978528b8b82abdce3e1e557ebbb6524a15c6c6a9/src/pages/CHANGELOG.md#2405---2024-05-29) KIT routes.
- TRG routes (leading zero e.g. [TRG-5-01](https://github.com/eclipse-tractusx/eclipse-tractusx.github.io/blob/978528b8b82abdce3e1e557ebbb6524a15c6c6a9/docs/release/trg-5/trg-5-01.md) / no leading zero [TRG-1-04](https://github.com/eclipse-tractusx/eclipse-tractusx.github.io/blob/978528b8b82abdce3e1e557ebbb6524a15c6c6a9/docs/release/trg-1/trg-1-4.md#L4)) -> recommend to use leading zero

### Expected Behavior

consistent naming of routes allows automation of e.g. changelog creation

What whould be needed:
- Workflow for PR enforcing a name scheme
- cleanup
