Support-0.19 - Githubissues

Description

Close #46

Change pinning from to >=0.19.0,<0.20.0. While it is not strictly necessary to drop support for 0.19.0, I don't want to handle slight compatiblity issues (mostly just for tests), and I don't want to commit to support more than the current major version of kedro.
Use ruff all across the codebase, and remove black. Relint the project
Use kedro-datasets because datasets are no longer included to core kedro in 0.19.x. Rename all reference of DataSet to Dataset across the codebase to match new convention.
Slightly update test to fix issues with post_gen_hooks
