[Documentation] Broken link to Bert Fine-Tuning examples page

[animohan]

In the documentation here : https://github.com/dmlc/gluon-nlp/blob/master/docs/examples/sentence_embedding/bert.md in the "Conclusion" points to this broken link ( https://github.com/dmlc/gluon-nlp/blob/master/docs/model_zoo/bert/index.rst) for referencing other fine tuning scripts.

This probably needs to reference this page: - https://gluon-nlp.mxnet.io/master/model_zoo/bert/index.html

@animohan thanks for raising this issue. This markdown is used to render the notebook that you can find here: http://gluon-nlp.mxnet.io/master/examples/sentence_embedding/bert.html. That's the link we originally intended for it to work.

That said, I understand that It indeed might be a bit confusing since people may read the markdown directly. I will keep this issue open for collection suggestions on how to avoid this confusion

@szha what about always reference to the github folder (e.g. ../../../scripts/bert), and adding a .htaccess file to our web server so that gluon-nlp.mxnet.io/scripts/bert are redirected to modelzoo/bert? We also need to make sure modelzoo/bert displays correctly (defaults to modelzoo/bert/index.html)

Redirection should work, though my worry is it might be error prone. The links that include 'scripts' are currently manually replaced in the makefile.

The solution to this issue is tracked in #894.
