Added "Tileset > Edit Tileset Image Parameters..." action

This makes the functionality easier to discover. Previously editing the tileset image parameters was only possible by clicking the value of the Image property in the Properties view, and then the appearing "Edit" button.

⚡ Key issues to review Code Duplication The method updateActions is introduced to replace updateAddRemoveActions, but the new method is almost identical to the old one with the addition of enabling/disabling mEditTilesetParameters. Consider refactoring to avoid duplication and enhance maintainability. UI Consistency Ensure that the new menu actions added for editing tileset parameters are consistent with existing UI design and user expectations. This includes checking alignment, spacing, and interaction behavior within the menu.

Oh well, the agent failed to understand a line was added to a function rather than a "duplicate" being added. For a moment I thought it might have caught the duplication between TilesetEditor::editTilesetParameters and TilesetParametersEdit::buttonClicked, but no, I think the latter was likely not in the context.
