Slight inaccuracy in NStepGRU docs

[euler16]

in the part where the input dimension has been described , I think it should be L_t instead of L_i

if u could tell me the procedure to make the changes, I can make the correction and do a PR myself.

It seems #5979 missed some fixes. Could you make a PR? The contribution guide is https://docs.chainer.org/en/latest/contribution.html.

while trying to build the documentation, I am getting the following error

'source file: {}'.format(source_abs_path))
RuntimeError: Couldn't parse root directory from source file: /home/rajivratn/anaconda2/envs/chain/lib/python3.6/site-packages/chainer/serializer.py

@toslunar after searching the codebase, i think the error is emanating from conf.py in doc/src.
could you tell me how to fix this?
