Update deployVotingProcess to accept and use proposals parameter.

The function signature on line 12 of contracts.js accepts only 4 parameters (name, description, startDate, endDate), but CreateProcessPage.js calls it with 5 arguments, passing _formattedProposals as the 5th parameter. This parameter is currently ignored. The function must be updated to accept proposals and pass them to the contract's createVotingProcess method.

🤖 Prompt for AI Agents 
In anonymousVoting/clientAnonymousVoting/src/components/CreateProcessPage.js
around lines 42 to 76, CreateProcessPage passes a fifth parameter
(_formattedProposals) to deployVotingProcess but the function in contracts.js
only accepts four params and ignores proposals; update the deployVotingProcess
signature to accept a proposals parameter, include that parameter in the call to
the smart-contract method (e.g., pass proposals to contract.createVotingProcess
as the proposals argument), ensure proposals are validated/serialized in the
same format expected by the contract, propagate errors as before, and update any
other callers/tests to pass the proposals argument if necessary.
