Publisher window as dialog

[iLLiCiTiT]

Changelog Description

Changing back Publisher window to QDialog.

Additional info

The reasoning for changing it to QWidget was to avoid having window always on top, which QDialog might cause on it's own (even without AlwaysOnTop flag). But it was found out that using QWidget with Window flag did break window positioning for some DCCs and broke stylesheets for almost all of them, especially when parent was passed to init. The reason why that happens was not revealed.

At the same time there was random behavior in substance painter where the publisher tool was moved under substance without any user interaction, when parent was not passed in, and had broken stylesheets when parent was passed in.

This might again raise issues when a DCC opens dialog that is modal, it might show under publisher and block the process.

Testing notes:

1. Publisher should show ok in all DCCs

• [x] Blender
• [x] Maya
• [x] Max
• [x] SPainter
• [x] Photoshop
• [x] Nuke
• [x] Resolve

• [x] Flame
• [ ] Harmony

Performed test in SP the Publisher window seems behaving ok in terms of focus and not being always on top but there is still that weird enlarging issue of the window present... not sure if related to this PR or if it should be ignored atm.

the UI progressively grows to the right of the screen infinitely

Might be worth having a checklist of DCCs to tick off as we test them.
