Can't reference token from other productionlist's if its group name contains hypens #11854
Description
Describe the bug
BTW, this poses problems only references inside of some productionlist directive. Outside of the production list it's possible to use cross-references like :token:`~python-grammar:with_item`.
This affects CPython docs, see python/cpython#108184 for a proposed workaround.
How to Reproduce
$ cat index.rst
.. productionlist:: a-foo
digit: "0".."9"
.. productionlist:: b
hexdigit: `a-foo:digit` | "a".."f"
