Silver and Electrum (Increased functionality for Gold)

As it stands, gold isn't great. My proposal is a new ore, silver. >Silver would be more common than gold, around the same level as Iron (with an added spawning buff in Birch Forests, to give more reason to go there?) >On its own, silver would be primarily decorative, with some additional use taking over the powered rail recipe. >Silver's primary function would be upgrading Gold tools, similar to how Netherite works. Electrum is a metal combination of Gold and Silver. Electrum tools would fill the progression gap between Iron and Diamonds (which are rare enough you only ever use them enchanted) > Electrum upgrade templates could be found in mid-game structures, like village blacksmiths, pillager outposts, and woodland mansions.
