Issue template (#8)

.github/ISSUE_TEMPLATE.md

-## Description of your problem or feature request
-
-First, carefully read the following to determine whether or not you have a valid Pytensor issue:
-
-- Does your issue only arise in a library that uses Pytensor (e.g. PyMC)?  If so, submit your issue to that library's issue tracker.  From there, the Pytensor-specific details can be worked out and a valid Pytensor issue can be identified.  **Issues framed primarily in third-party libraries are liable to being marked as invalid and closed.**
-- Does your issue involve OS and/or environment-specific settings (e.g. installation and/or compilation issues)?  If so, create a [Discussion](https://github.com/pymc-devs/pytensor/discussions) instead.  From there, we can help determine whether or not the issue is due to faulty logic in Pytensor (i.e. a valid issue) or something specific to your local setup.
-
-
-If the above does not apply, and you have an issue or feature request that's specific to Pytensor, provide a minimal, self-contained, and reproducible example (i.e. an [MWE](https://en.wikipedia.org/wiki/Minimal_reproducible_example)):
-
-```python
-[Your code here]
-```
-
-**Please provide the full tracebacks for any relevant errors and/or warning messages.**
