Feat/subnet contract versioning

[jbencin]

Description

Add Semver versioning to subnet.clar L1 contract. Also, check version of subnet.clar from application and multi-miner.clar

Applicable issues

• fixes Add versioning to L1 subnet.clar contract #269

Additional info (benefits, drawbacks, caveats)

• In get_l1_contract_version(), I used an arbitrary address I pulled from test code for sender. Since this call is to a read-only function, I don't think it matters what is used here
• This calls get_l1_contract_version() every time that submit_commit() is called to submit a block. Maybe this only has to be done once and cache the result?

Checklist

• Test coverage for new or modified code paths
• Changelog is updated
• Required documentation changes (e.g., docs/rpc/openapi.yaml and rpc-endpoints.md for v2 endpoints, event-dispatcher.md for new events)
• New clarity functions have corresponding PR in clarity-benchmarking repo
• New integration test(s) added to bitcoin-tests.yml
