[DOCS] Navbar links in README.md do not navigate: anchor mismatch for Learning Paths, Getting Started, Community

## Problem

The navbar links defined at the top of `README.md` are not navigating correctly to their respective sections.

Current navbar:

```html

Website •
Learning Paths •
Getting Started •
Community

```

However, the corresponding section headers in the README are:
```md
## 🗺️ Learning Paths
## 🚀 Getting Started
## 👥 Community
```
## Issue

`#roadmap` - No matching `id="roadmap"` or `## Roadmap` section (the section is `## 🗺️ Learning Paths`)

`#getting-started` - May not resolve correctly due to emoji in header (`## 🚀 Getting Started`)

`#community` - May not resolve correctly due to emoji in header (`## 👥 Community`)

GitHub auto-generates anchor IDs based on the rendered heading text (including emoji handling), which may not match the hardcoded navbar anchors.

## Expected Behavior

Clicking:

- Learning Paths should scroll to `## 🗺️ Learning Paths`
- Getting Started should scroll to `## 🚀 Getting Started`
- Community should scroll to `## 👥 Community`

## Suggested Fix

### Option 1 (Recommended): Update navbar anchors to match generated IDs

Inspect the generated anchor IDs on GitHub and update links accordingly. Most likely:

```html
Learning Paths
Getting Started
Community
```

> (Exact IDs should be verified from GitHub-rendered headings.)

### Option 2: Remove emojis from section headings

Change `## 🗺️ Learning Paths` to `## Learning Paths`

This ensures predictable anchor IDs:

`#learning-paths`
`#getting-started`
`#community`

### Option 3: Add explicit anchor IDs

Add manual anchors above sections:

```html

## 🗺️ Learning Paths
```

## Impact

- Improves navigation usability
- Prevents confusion for new users
- Enhances overall documentation quality

If approved, I can open a PR to fix the anchor mismatch.
