Clean up examples/ directory

Clean up examples/ directory #573

[mattdangerw]

It would be nice to keep some sort of minimal content in the README...

# KerasNLP Examples

The `examples/` directly contains scripts built on top of the library that do not fit well into
the colab format used on [keras.io](https://keras.io/examples/). This includes recipes for
pre-training models and evaluating models on benchmarks such as GLUE.

We should do some light renaming of the content in this directory and fix all import after renaming.

• Rename /examples/bert/ -> /examples/bert_pretraining/
• Delete the file bert_finetune_glue.py (we now have better code in the glue_finetuning directly).
• Rename the file bert_train.py -> bert_pretrain.py.
• Rename the file bert_preprocess.py -> bert_create_pretraining_data.py.

@chenmoneygithub do those renames look ok to you as well?

Thanks mattdangerw, I add this to readme 👍🏻

Hey @chenmoneygithub can I make this changes, If those renames look ok ?

• Rename /examples/bert/ -> /examples/bert_pretraining/
• Delete the file bert_finetune_glue.py (we now have better code in the glue_finetuning directly).
• Rename the file bert_train.py -> bert_pretrain.py.
• Rename the file bert_preprocess.py -> bert_create_pretraining_data.py.

@ADITYADAS1999 thanks! This looks good!

We will also need to update the README here -> https://github.com/keras-team/keras-nlp/blob/master/examples/bert/README.md to reflect the script renames. Should be a simpler find and replace.

Also can we delete this section entirely? https://github.com/keras-team/keras-nlp/blob/master/examples/bert/README.md#evaluating-bert-with-glue. We are removing the script on this PR.

what kind of changes should I change here in the docs? can you suggest little bit.

In my opinion we have to remove this section, as we remove the bert_finetune_glue.py file. kept this extra section generate confusion for new maintainers and contributors in future.

Sure!

• Let's delete this section -> https://github.com/keras-team/keras-nlp/blob/master/examples/bert/README.md#evaluating-bert-with-glue
• Let's update the names of this scripts that have changed elsewhere in the README, for example ->
