Bump Version To 1.0.0

[jvanderaa]

To help alleviate issues with Poetry zero-based resolution, it may be good to move this to a 1.0.0 release. If poetry add nornir-jinja2 is executed, Poetry will add the item as nornir-jinja2 = "^0.1.1" to the pyproject.toml file. The way Poetry handles this resolution is to allow 0.1.x to be installed. So newer users to Poetry will need to modify the pyproject.toml to being nornir-jinja2 = "^0" to get the desired resolution in similar fashion to 1.x and 2.x releases.

This is not a requirement by any means, but maybe an idea for the releases to help those just getting started and using Poetry for package management.
