Changing 'stable' to 'latest' in notebooks in examples

[bcui19]

Updating the URLs in docs with the newly generated links.

Remade the PR for CO-965.

I wasn't able to track down a few of the links:

./examples/streaming_dataloader_facesynthetics.ipynb:32: "[streaming_dataset]: https://docs.mosaicml.com/en/stable/api_reference/composer.datasets.streaming.dataset.html#composer.datasets.streaming.dataset.StreamingDataset\n”,

./examples/streaming_dataloader_facesynthetics.ipynb:33: "[streaming_dataset_writer]: https://docs.mosaicml.com/en/stable/api_reference/composer.datasets.streaming.writer.html#composer.datasets.streaming.writer.StreamingDatasetWriter”

./examples/streaming_dataloader_facesynthetics.ipynb:268: "[api]: https://docs.mosaicml.com/en/stable/api_reference/composer.datasets.streaming.writer.html#composer.datasets.streaming.writer.StreamingDatasetWriter"

./examples/streaming_dataloader_facesynthetics.ipynb:326: "For more information on the StreamingDataset parent class check out the API reference."

./examples/glue/glue_entrypoint.ipynb:115: "[trainer_hparams]: https://docs.mosaicml.com/en/stable/api_reference/composer.trainer.trainer_hparams.html?highlight=trainerhparams#composer.trainer.trainer_hparams.TrainerHparams\n"

Let me know what would be good to do with the above links.

LGTM other than one typo. I manually checked all the changed URLs (changing stable to latest to preview how they'll show up in the next release). I didn't check whether there are other broken links in the docs--just gonna assume this got them all and we can fix it later if we find more.

As far as the stuff you couldn't find URLs for: the Streaming dataset links can't be fixed until the Streaming V2 docs get written. And YAHP is getting removed / that whole tutorial will need a lot of refactoring, so that one is probably fine. Would be great if you could open a JIRA issue documenting that these links still need to get fixed so we don't lose track of this.
