Misnamed pastel option

[ghost]

I came to this issue while running poetry. My setup involves:

• python 3.8.1
• poetry-1.0.0
• cleo-0.7.6
• clikit-0.4.1
• pastel-0.2.0

In clikit-0.4.1, option "underscore" is adapted from "underline". See the following snippet: https://github.com/sdispater/clikit/blob/0.4.1/src/clikit/adapter/style_converter.py#L19.

Thus, when running poetry, the following error occurs:

$ python -V
Python 3.8.1
$ poetry

For further detail on the pastel side, this is what pastel expects as valid options: https://github.com/sdispater/pastel/blob/0.2.0/pastel/style.py#L48

clikit 0.4.1 is not compatible with pastel 0.2.0 as you can see here : https://github.com/sdispater/clikit/blob/master/pyproject.toml#L20

I don't know how you ended up with this set of package versions but they are not expected to work together.
