Description:

In the latest version of `python-pygls` (0.10.3-1), the package is installed in the usual path (/usr/lib/python3.9/site-packages) with version 0.0.0.
```
- /usr/lib/python3.9/site-packages/pygls
- /usr/lib/python3.9/site-packages/pygls-0.0.0-py3.9.egg-info
```

The following python script returns `0.0.0`
```python
from importlib.metadata import version
print(version('pygls'))
```

If the package is installed "by-hand" following the steps below:
* download the source files by either pythonhosted.org or github.com
* install as user or globally (sudo) with `pip install` or `python setup.py install`
the package reports the expected value for its version (0.10.3).

Even if following step by step the PKGBUILD found at the [github mirror](https://github.com/archlinux/svntogit-community/blob/packages/python-pygls/trunk/PKGBUILD)

```
build() {
cd $_name-$pkgver
python setup.py build
}

check() {
cd $_name-$pkgver
pytest
}

package() {
cd $_name-$pkgver
python setup.py install --root="$pkgdir" --optimize=1 --skip-build
}
```
then the installed package still reports the right version.

I've reported upstream (https://github.com/openlawlibrary/pygls/issues/189) but realized soon that following the "manual process" gave no issues.
