36669	Document `Negative indexing is not supported` for slicing F() expressions	AJ Collins		"I was planning to use F() expression slicing to take off the last character of a field. I was met with `ValueError: Negative indexing is not supported.` 

I'd like to update the docs for https://docs.djangoproject.com/en/6.0/ref/models/expressions/#slicing-f-expressions

 I have a PR ready to go as well"	Cleanup/optimization	new	Documentation	5.2	Normal			AJ Collins	Unreviewed	1	0	0	0	0	0
