[DOC] Error messages should refer to Numba-CUDA

[gmarkall]

Some of the vendored error messages refer to issues as coming from Numba, and not Numba-CUDA.

Example: #561 (comment)

numba-cuda/numba_cuda/numba/cuda/core/errors.py

Lines 435 to 450 in 7ce01f4

	typing_error_info = """
	This is not usually a problem with Numba itself but instead often caused by
	the use of unsupported features or an issue in resolving types.
	To see Python/NumPy features supported by the latest release of Numba visit:
	https://numba.readthedocs.io/en/stable/reference/pysupported.html
	and
	https://numba.readthedocs.io/en/stable/reference/numpysupported.html
	For more information about typing errors and how to debug them visit:
	https://numba.readthedocs.io/en/stable/user/troubleshoot.html#my-code-doesn-t-compile
	If you think your code should work with Numba, please report the error message
	and traceback, along with a minimal reproducer at:
	https://github.com/numba/numba/issues/new?template=bug_report.md
	"""

The message should be updated to guide the user towards Numba-CUDA information.

@gmarkall seems like simple fix. Can I work on this to familiarize myself with the codebase?

@kaeun97 Thanks for offering!.. I have quite particular guidance in mind for the error messages and associated information, so I fear that if you were to submit a PR for this, my feedback would be along the lines of "please write it exactly like this: <...>" to the point where it was a bit of a waste of your time. So, although I'm glad of and grateful for your contributions, I think your kindly-contributed time is likely best spent on other issues / items.

Many thanks!

Makes sense! Thanks for the explanation!
