chore: remove react-jss (#5907)

BREAKING CHANGE: UI5 Web Components for React is no longer relying on `react-jss` internally, hence the dependency is now removed and the `react-jss` ThemeProvider is no longer rendered as part of our `ThemeProvider`. If you are relying on `react-jss` in your application, please make sure to render your own `react-jss` ThemeProvider.
BREAKING CHANGE: The `useResponsiveContentPadding` has been removed. You can achieve the same look and feel by using the [responsive content padding from Common CSS](https://sap.github.io/ui5-webcomponents-react/main/?path=/docs/knowledge-base-common-css--docs#content-paddings).

+### Removed `react-jss`
+
+UI5 Web Components for React is no longer relying on `react-jss` internally, hence the dependency is now removed and the `react-jss` ThemeProvider is no longer rendered as part of our `ThemeProvider`.
+If you are relying on `react-jss` in your application, please make sure to render your own `react-jss` ThemeProvider:
+
+```tsx
+import { ThemeProvider } from '@ui5/webcomponents-react';
+import { ThemingParameters } from '@ui5/webcomponents-react-base';
+import { ThemeProvider as ReactJssThemeProvider } from 'react-jss';
+
+function MyRootComponent() {
+  return (
+    <ThemeProvider>
+      <ReactJssThemeProvider theme={ThemingParameters}>{/* your app content goes here */}</ReactJssThemeProvider>
+    </ThemeProvider>
+  );
+}
+```
+
+## Removed hooks
+
+### `useResponsiveContentPadding`
+
+The `useResponsiveContentPadding` hook has been removed.
+You can now apply responsive content paddings by applying the `sap-content-paddings-container` class from `@sap-ui/common-css` package to your element.
+You can find a more detailed documentation [here](https://sap.github.io/ui5-webcomponents-react/main/?path=/docs/knowledge-base-common-css--docs#content-paddings).

-The `useResponsiveContentPadding` hook is a hook generating a style class or a tuple containing the style class and the current range if `returnRangeString` is set to `true`.
-It adds `padding-left` and `padding-right` corresponding to the range (retrieved with `Device.getCurrentRange()`) of the element.

 In case you already have an existing Next.js project and want to add UI5 Web Components for React to it, you first need to follow our [general Getting Started Guide](https://sap.github.io/ui5-webcomponents-react/?path=/docs/getting-started--docs#add-ui5webcomponents-react-to-an-existing-app).
 
-As UI5 Web Components for React is using `react-jss` internally, you need to apply some changes to your `_app` and `_document` file (in case you are using the pages router).
-You can copy these changes either from the official [next.js-react-jss example](https://github.com/vercel/next.js/tree/canary/examples/with-react-jss) or from our [pages router template](https://github.com/SAP/ui5-webcomponents-react/tree/main/examples/nextjs-pages).
+For a better SSR support, we recommend importing our stylesheet bundle inside the `_app` file or the root layout (depending on whether you are using the pages or the app router) and set the `staticCssInjected` prop on our `ThemeProvider`:
+
+```tsx
+import '@ui5/webcomponents-react/styles.css';
+
+export default function AppOrRootLayout() {
+  // ...
+  return (
+    // ...
+   <ThemeProvider staticCssInjected>
+   // ...
+   </ThemeProvider>
+  )
+}
+```
 
-In case you are already using the app router, you can copy the `react-jss` setup from the `app/CssRegistry.tsx` in our [app router template](https://github.com/SAP/ui5-webcomponents-react/tree/main/examples/nextjs-app). Make sure to add this component to your root layout!
