Upload CW3 Fixed Multisig

We are Apollo DAO and are proposing the upload of the CW3 Fixed Multisig contract to enable the deployment of Apollo Safe. Follow this link to see more about Apollo Safe's value proposition and use cases: https://articles.apollo.farm/deploying-apollo-safe-to-osmosis-and-injective/. The CW3 Fixed Multisig code can be found here: https://github.com/apollodao/cw-plus-fork/tree/v0.13.2-branch. The Stargate feature from the cosmwasm-std package is enabled and the checksum of the wasm file is 8ec0b9ba0419c682695e74c16379db5d268289bbc863b043091ae968cdc55718 using workspace-optimizer 12.6.
