Use of MUI component instead of shared component

[oyo]

Current Behavior

Some times code uses MUI components directly where better alternatives exist.

Expected Behavior

We created the Shared Components to simplify development and preconfigure MUI components for our style. They should be used whenever possible.

Steps To Reproduce

Example:
https://github.com/eclipse-tractusx/portal-frontend/blob/main/src/components/overlays/AddMultipleUser/index.tsx#L25
Typography exists in the shared components

@manojava-gk could you please verify this once and adjust the implementation where needed

@jjeroch this has been merged to dev because it's a fully backwards compatible pure technical change using our shared components instead of direct MUI imports.
