Support plette version 1.0.0

[krishnasism]

On using pipenv-setup, you will get an error called plette.models not a package.

from pipenv_setup import pipfile_parser as parser

This is because the underlying plette package was updated to 1.0.0 with some breaking changes.

For now I just downgraded the version of plette to use pipenv-setup, but @Madoshakalaka you might want to look into it

will see if either I or some of the guys has bandwidth to address this one.

I have some time this week if you don't have someone to look into it. But I'm not familiar with your codebase. I can get up to speed (if you need)

@krishnasism , for sure! I'm a bit tight on time but I'm coaching some of our folks at GuayaHack, our tech collective, on Discord and shepherding the process of getting a fix out. Feel free to join us there 👍🏼 ( in case you prefer to independently work on this, feel free to tag me in case you need help )
