Conflicts: - rs/nns/governance/src/pb/conversions/mod.rs :: Conflict seems to arrise from the fact that in master, some code was deleted right next to where I added some code. `git diff --cached master` seems to indicate that I preserved my addition while also preserving the deletion in master.

# Motivation There are two new proposal types `TakeCanisterSnapshot` and `LoadCanisterSnapshot ` introduced [here](dfinity/ic#8317) and [here](dfinity/ic#8283). This PR manually bumps the version of the monorepo for the `nns` package. # Changes 1. Checked out top of IC repo. 2. Ran `scripts/import-candid ../ic`. 3. Ran `scripts/compile-idl-js`. 4. Reverted files outside packages/nns. 5. Updated `Action` types. # Tests - Added unit tests. # Todos - [x] Add entry to changelog (if necessary).

Previous Work
Previously, I tried to do this in PR 8228, but during code review, radical changes were requested; hence this new PR. Concretely, in the previous PR, the new proposal type was implemented as an NnsFunction; whereas, here, it is implemented as a direct Action. The rationale for switching is that the it was requested that the topic of this TakeCanisterSnapshot depend on the target canister, which means that the Governance canister cannot treat the arguments of the proposal as an opaque blob (when determining the proposal's topic).
