bot: Update sns_aggregator candid bindings

[pr-automation-bot-public]

Motivation

A newer release of the internet computer is available.
We would like to parse all the latest SNS data. To do so, we update the candid interfaces for the SNS aggregator.
Even with no changes, just updating the reference is good practice.

Changes

• Update the version of IC_COMMIT_FOR_SNS_AGGREGATOR specified in config.json.
• Updated the sns_aggregator candid files to the versions in that commit.
• Updated the Rust code derived from .did files in the aggregator.

Tests

• Please check the API updates for any breaking changes that affect our code.
  Breaking changes are:
  • New mandatory fields
  • Removing mandatory fields
  • Renaming fields
  • Changing the type of a field
  • Adding new variants
