Replace 'fasttext' with 'fasttext-wheel' in requirements_nlp
**Describe the bug**

It is not possible to install the requirements of the NLP component because the fasttext wheel cannot be build any more. However, there is a fork called fasttext-wheel that can be installed with pip. I have tested it extensively and it works with NeMo

**Steps/Code to reproduce bug**

```
pip install -r requirement/requirements_nlp.txt 
```

**Expected behavior**

To be able to install NLP component of the NeMo toolkit without having to hack the requirements_nlp file each time.

**Environment overview (please complete the following information)**

 - Environment location: Bare-metal
 - Method of NeMo install:  pip and source

```
pip install "git+https://github.com/NVIDIA/NeMo.git@main#egg=nemo_toolkit[all]"
```

or  (from source)

```
pip install -e ".[all]"
```

**Environment details**

- OS version : Manjaro Linux (current)
- PyTorch version: Nightly builds with Cuda 12.1 (pip)
- Python version: 3.8.18 (NeMo does not work with more recent Python versions)
