A brief visit to the code indicates that there is a bigger problem, in that the ampacity of 8Ga copper is only 55 at 90C (aluminum 45 Amps) so your wire is too small for a 100 amp service. You need a bare minimum (if everything is rated for 90C) of 3Ga copper or 2Ga aluminum, and probably larger after various derating factors are applied, or if 75C is the limit on any connection.

Remember you need 4 wire , 2 hot a ground and a neutral. Since it is detached you will also need a grounding electrode. If the 50 amp GFCI panel is in the shop ok but I would not recommend a GFCI feeder from your main panel, that’s a long way to walk for trips.
