add H100 to supported GPUs

[asaiacai]

Fixes #2317

I manually tested with using the CLI

$ sky show-gpus --cloud lambda
COMMON_GPU  AVAILABLE_QUANTITIES  
A10         1                     
A100        1, 2, 4, 8            
A100-80GB   8                     
H100        1                     
V100        8 

$ sky show-gpus --cloud aws
COMMON_GPU  AVAILABLE_QUANTITIES  
A10G        1, 4, 8               
A100        8                     
A100-80GB   8                     
H100        8                     
K80         1, 8, 16              
M60         1, 2, 4               
T4          1, 4, 8               
V100        1, 4, 8

Tests should be unrelated (#2320; cc @cblmemo). Merging this.

Yes, I believe this is an unrelated problem... It got the same error number as I do 🤔
