Update juvix-stdlib to remove non-ASCII indentifiers (#2857)

This PR updates the juvix-stdlib to the current main commit which
includes:

* https://github.com/anoma/juvix-stdlib/issues/59
* https://github.com/anoma/juvix-stdlib/issues/101

All the Juvix test suite files and examples in this repo have been
updated to be compatible with the new stdlib.
