bot: Update proposals candid bindings (#7696)

# Motivation
We would like to render all the latest proposal types.
Even with no changes, just updating the reference is good practice.

# Changes
* Update the version of `IC_COMMIT_FOR_PROPOSALS` specified in
`config.json`.
* Updated the `proposals` candid files to the versions in that commit.
* Updated the Rust code derived from `.did` files in the proposals
payload rendering crate.

# Tests
- [ ] Please check the API updates for any breaking changes that affect
our code.
  - [ ] Please check for new proposal types and add tests for them.

Breaking changes are:
  * New mandatory fields
    * Removing mandatory fields
    * Renaming fields
    * Changing the type of a field
    * Adding new variants
