String transparency apply when player interacts while holding shears

The recent change of the String texture made some people upset, and it will ruin some builds as Strings are now more visible, for example, String can be used to prevent saplings from growing, it can also be used to have carpets on air to make umbrellas.

So my solution to this would be to make the String texture have it's old transparency when the player interacts with the String while the player holds Shears.

This would keep the recent change, while allowing players to not have strings be too visible in their builds
