Move the cli_toolkit_repository to the right structure

[yehudarav]

The CLI in hera is built as follows:

1. A argparser in the /bin directory
2. A CLI file in the relevant module that runs the commands. Usually, the CLI invokes a toolkit, and therefore the implementations in CLI.py will load the toolkit and call the right functions.

The cli_repository is implement in the utls/data/cli_toolkit_repository.

It mixes the definition of the argparse and the implementation. Please move it to the right place.

Please note that the python in the bin files have the

#! /usr/bin/env python

That makes it an executable file. They also don't have a .py extension and they are executables.

I reviewed cli_toolkit_repository and verified that it is no longer used by the current CLI flow.
The dynamic toolkit and experiment loading is now handled via hera-toolkit, hera-project, and the repository mechanism, so this file was effectively obsolete.

To make sure nothing breaks:

I removed the unused cli_toolkit_repository code.

I updated all notebooks that previously referenced it (Hera_Dynamic_Toolkits_Quickstart, Hera_Dynamic_Toolkits_Tutorial, IMS_Tutorial, Jerusalem_Tutorial) to use the current CLI and repository commands.

I added integration and unit tests to validate dynamic loading of experiments and toolkits via the new flow.

With these changes, the CLI responsibilities are now clearly separated:

hera/bin contains only argument parsing and command dispatch.

The actual logic lives in the relevant modules and toolkits.

Documentation and tutorials are aligned with the current, supported API.
