Typo in INSTALL.md

[SebastianBezold]

Description

The instructions on how to install the Helm chart do contain a typo/wrong reference.

Adding the repo is done with a one name and further helm commands use a separate name. This would lead do issues when copy-pasting the examples for local use.

Expected

Helm repo names mentioned in install docs should match and be consistent.
Suggestion: Stick with tractusx-dev as name, since it contains all charts release in the GitHub org
