chore: Align Application namespace creation and readme script(#213)

[alezander86]

Description:

This pull request updates the values files for the App of Apps structure by modifying the namespace definitions for multiple applications. The changes ensure that namespace values are sourced correctly from values.yaml, making them more flexible and consistent. If any additional updates are required for other applications, they should follow this structure.

Additionally, the Makefile script has been updated to modify the README table of applications, adding a new column with the namespace name.

Fixes (#213)
