Refactor helpClicked() method in AlgorithmDialog

[darshdinger]

Description of work

This pull request refactors the helpClicked() method in AlgorithmDialog to utilize InterfaceManager for displaying algorithm help instead of directly calling HelpWindow. This change is necessary to enable the integration of the new Python-based HelpWindow implementation while maintaining backward compatibility with existing functionality.

Currently, this refactor leads to a segmentation fault and core dump (crash) when using the algorithm help button, which will require further investigation and resolution.

Summary of work

• Refactored helpClicked() Method:

  • Replaced the direct call to HelpWindow::showAlgorithm with a call to InterfaceManager().showAlgorithmHelp.
  • This modification aligns the method with the updated design for help functionality that supports the Python-based HelpWindow.

• Purpose of the Refactor:

  • Facilitates the transition to the Python-based HelpWindow by leveraging InterfaceManager as a single point of entry for help functionality.
  • Simplifies the maintenance and future extension of help-related features.
