Update IC commit in snsdemo (#366)

# Motivation

#365 failed to update the IC
commit automatically, because sns CLI was changed in
https://gitlab.com/dfinity-lab/public/ic/-/merge_requests/19803 to
require human interaction.

# Changes

1. Update IC commit
2. Pass `--skip-confirmation` to  `sns propose`.

# Tested

CI passes again
