[Unknown Mod][Locations][Shrines] Display the spell graphic in the shrine window when the hero visiting it already has the spell or cannot learn it

[LeHerosInconnu]

Display the spell graphic in the shrine window when the hero visiting it already has the spell or cannot learn it.
The spell graphic is displayed between the first part of the text and the end of the text.

In the example, between:

"...spell - 'Bless'.", and "...spell - 'Paralyze'."

And:

"Unfortunately, you..."

Reference windows: (click to expand)

The hero learns the spell:

The hero already knows the spell:

The hero does not have a magic book:

The hero does not have the wisdom to learn the spell (third circle shrine, with the paralyze spell):

A specific sound, indicating “disappointment,” is also played when this happens.
This also allows the player to right click on the spell graphic to display the spell information window.

This is not an option.
This can be implemented directly in fheroes2.
