feat: makeProposal return created proposal ID

[peterpeterparker]

Motivation

makeProposal returns currently void which is a bit inconvenient if the caller needs to know which proposal was created which happens to be the case in the small proof of concept I was developing.

Therefore this PR extends the function to return the potential ID of the proposal that was created.

Notes

Given the fact that the answer of the Governance canister is a variant I hesitated between returning Promise<bigint | undefined> or {success: boolean; proposalId?: bigint}. Given the fact that there was no use cases where `success: false^ would be set, I opted for the first simple solution.

Changes

• return Command_1 for manageNeuron
• return the proposal ID for makeProposal
• make other functions that uses manageNeuron continue returning void
