Remove unnecessary steps in explorer/converter modals

[Irozuku]

This pull request streamlines the notebook tool configuration workflow by conditionally skipping the parameter configuration step when the selected tool does not require additional parameters. It achieves this by checking the presence of properties in the tool's schema and updating navigation logic and button labels accordingly. The changes affect both converter and explorer creation flows for a more intuitive user experience.

Conditional step navigation and workflow improvements:

• The configuration steps in ConfigureToolModal.jsx are now dynamically set: if the tool's schema has properties, both "Configure Scope" and "Configure Parameters" steps are shown; otherwise, only "Configure Scope" is presented.
• In both converter and explorer creation flows (FormConverterSection.jsx, FormExplorerSection.jsx), the navigation after the scope step is updated: if no parameters are required, the process skips directly to saving the tool; otherwise, it proceeds to the parameter configuration step. [1] [2]

Component interface and button label updates:

• The ScopeStepConverter.jsx and ScopeStepExplorer.jsx components now receive a nextStep callback instead of setStep, allowing conditional navigation logic. [1] [2]
• The button labels in the scope and parameter steps are dynamically set: "Next" when parameters are required, otherwise "Create Converter" or "Save"/"Create Explorer" as appropriate. [1] [2] [3] [4]
