* [Issue template] need to update/extend who to tag
1. need to update who to tag for `tensorflow`
2. also requesting to add someone to tag for models hub issues - perhaps separate sub-entries for UI and code - e.g. I don't know who to tag for broken models: https://github.com/huggingface/transformers/issues/10726
Thanks.

* Create PULL_REQUEST_TEMPLATE.md
Proposing to copy this neat feature from pytorch. This is a small template that let's a PR submitter tell which issue that PR closes.
* Update .github/PULL_REQUEST_TEMPLATE.md
