Rename opt_name to name

[PythonFZ]

Lines 228 to 236 in 13142e1

	opt_name: str = "adam"
	emb_lr: NonNegativeFloat = 0.02
	nn_lr: NonNegativeFloat = 0.03
	scale_lr: NonNegativeFloat = 0.001
	shift_lr: NonNegativeFloat = 0.05
	zbl_lr: NonNegativeFloat = 0.001
	transition_begin: int = 0
	opt_kwargs: dict = {}
	sam_rho: NonNegativeFloat = 0.0

I suggest going from:

optimizer:
  opt_name: adam
  opt_kwargs: ...
  emb_lr: 0.01
  nn_lr: 0.005
  scale_lr: 0.001
  shift_lr: 0.05
  zbl_lr: 0.001

to

optimizer:
  name: adam
  kwargs: ...
  emb_lr: 0.01
  nn_lr: 0.005
  scale_lr: 0.001
  shift_lr: 0.05
  zbl_lr: 0.001

to remove redundant information
