fix(deps): replace optional dependencies with dependency groups

Definition: https://packaging.python.org/en/latest/specifications/dependency-groups

The optional dependency table ([project.optional-dependencies]) is
supposed to be user-facing for installs of TagStudio. Meanwhile, the
replacement dependency groups is explicitly meant for extra development
tools, so lets use that.

This does mean the command for a full development environment has changed
from:
```sh
pip install -e '.[dev]'
```

To:
```sh
pip install -e . --group all
```

The documentation has been adjusted for a quick replacement, but
probably should have more information on a later time.
