trunk/2436449227d69c0a846b5ff1ae845b659d9da948: Fix typos in torch.nn.modules docstrings (#185603)

Fix various documentation typos across nn module docstrings: a

spurious "of" in AdaptiveLogSoftmaxWithLoss, double spaces and an

extra parenthesis in batch normalization modules, "sizes" → "sides"

in transposed convolution notes, a missing "be" in FeatureAlphaDropout,

a missing "is" in MarginRankingLoss, and "it's" → "its" in upsampling

modules.
