Flow launch preparations

[smol-ninja]

As we are nearing launch of Flow, I have prepared a list of task (inspired from @razgraf's https://github.com/sablier-labs/v2-interfaces/discussions/1180):

Pre deployments

• Refactor and merge feat: flow examples evm-examples#37
• Refactor and add Integration templates for Flow. Resolved in a new repo.
• Include Codehawk reports in the audits repo. Resolved in #12.
• Merge feat: add flow deployments deployments#14
• Publish npm package: https://www.npmjs.com/package/@sablier/flow

Post deployments

• Merge refactor: restructure with lockup dir deployments#12 in deployments repo
• Add deployment addresses in docs: feat: add flow deployments addresses docs#201
• Merge test: run fork test against mainnet deployment #345
• Rename v2-deployments to deployments and update docs accordingly

The checklist is now complete.
