chore: remove poetry.lock and put in .gitignore (#758)

<!-- markdownlint-disable MD041-->
## Description

> poetry.lock in the git repo is causing many issues working in
different branches.
I think it's best to remove it for now and put it in .gitignore and try
to work like this.

**Related issue (if any):** fixes #issue_number_goes_here
