German normalization fails due to apparent installation problems.
**Describe the bug**

German normalization fails due to apparent installation problems.

**Steps/Code to reproduce bug**

If installed with:
`pip install nemo-toolkit[all]` the nemo_text_processing.text_normalization.de.taggers.tokenize_and_classify is not in the project in order to normalize german phrases although used in the nemo_text_processing/text_normalization/normalize.py file.

If installed with:
`python -m pip install git+https://github.com/NVIDIA/NeMo.git@main` the file nemo_text_processing/inverse_text_normalization/vi/taggers/money.py is not found.

If installed with:
`git clone -q https://github.com/NVIDIA/NeMo.git`
when normalizing, getting the following issue: [https://github.com/NVIDIA/NeMo/issues/3341]

**Expected behavior**
