Allow declaration of which dependency groups to install #5
Description
Poetry's install command can have the options --with, --without, --only or --only-root passed to it. It would be incredibly useful if this extra functionality could be extrapolated to this GitHub action through the inputs.
A list of group names could be passed to the --with, --without and --only flags, and a boolean could be used for the --only-root flag.
This would enable correct usage of Poetry's dependency system, where the tool.poetry.group.dev.dependencies are installed by default (this group should not be marked as optional = true within pyproject.toml), and are ignored when installing dependencies for installation for publishing to PyPi.
