Move _find_run_command from template to framework

[merelcht]

Description

#3051
Moved the _find_run_command method from the project template to the framework itself.

This is necessary refactoring to make running packaged Kedro better (#3237)

Development notes

In the first attempt I moved the find run logic to kedro.framework.project.__init__, because that's also where configure_project() is. However, with that solution there are direct imports from kedro.framework.project to kedro.framework.cli which breaks the contract we've setup.

 from kedro.framework.cli.utils import (
        KedroCliError,
        load_entry_points,
    )

from kedro.framework.cli.project import run

Contract: https://github.com/kedro-org/kedro/blob/main/pyproject.toml#L159

In order not to break the import contract, I've moved the find run logic to kedro/framework/cli/project.py

Note

The same change to __main__.py needs to be done on the starters side

LGTM! ✨

Shall we create a ticket on starters side?

It looks good in general. I wonder if you found the reason why this was necessary to be implemented in the starter side instead of kedro at first place?

It was implemented as part of making cli.py in the templates optional and the simple reason is that at the time this seemed the most logical place. When we later decided it should be moved, we never ended up prioritising because users didn't complain.
