Missing implementation for MarkovPasswordsGUI::renderHTMLFile

[ignis-sec]

This code should be extracted and parametrized from class constructor.
Open a html file with QT.

/** @brief Render a HTML file.
* @param filename - Filename of the html file. (relative path to the views folder).
*/
```

HTML render with an example. We used QTWebEngine method.

Please:

• Don't use absolute filepaths like C:/Users/Yunus/...
• Make this code parametrized, let the function take the filename from the function parameters
• Implement it in its own function in MarkovPasswordsGUI::renderHTMLFile in the class CPP file:line 26
• Send a commit&push with the code.

• Finally implemented with a function and using with a button.
