Description

Fix #3074 and #3075

Development notes

@SajidAlamQB Notes:

• Refactored utils.py and unstripped pyproject.toml and requirements.txt. We now handle removing headers from pyproject.toml using the toml library.

The current test suite is still asserting text, we should read the parse the file. I think this should be merged first #3230. There are not much points to fix the broken test if we are gonna change that.

Should https://github.com/kedro-org/kedro-starters/blob/main/spaceflights-pyspark/hooks/post_gen_project.py be updated to also mention "Kedro Viz" not in addons? The opposite of https://github.com/kedro-org/kedro-starters/blob/main/spaceflights-pandas-viz/hooks/post_gen_project.py

Nice spot! I don't think it really matters as the templates are decided in starters.py so where the add-ons work is concerned its not a problem. This was more of guard for users using the --starter flags as the default add-on in starters is none so as long as we have a check for any other add-on it won't run. But for consistency I think it would be nice to make them all aligned - it’s cleaner that way!

I've tried this out and the behaviour looks good! I found a coupling between the existence of the data folder and the SQLiteSessionStore config, but let's decide on that via Slack.

The only thing that's missing is just the docstring for the helper methods, but happy to approve when that's done 👍

[noklam]

I have fix the tests with toml and add some docstring for the new utils question. I leave a question whether these should be all public methods and maybe worth refactor later but not necessary to fix this in this PR.

Documented my observation in #3264
