Return 405 onforc index deploy unless forc-index version matches fuel-indexer version

[ra0x3]

• Indexers compiled with different fuel-indexer and forc-index versions always present issues
  • Because we can have non-trivial changes between even patch versions
• We should add a VERSION to the indexer module that indicates what version of forc-index it was compiled with
• When deployed via forc-index deploy if the compiled VERSION does not match the version of the service being used, should return a 405
• We might remove this of feature flag it in the future, but for now this tends to always be an issue

• For this, I'm wondering if it would be possible to add a const VERSION to the indexer modules, and then extract this VERSION on forc index deploy in fuel_indexer_api_server::uses::register_indexer_assets, and compare it to fuel_indexer_lib::config::IndexerConfig::version
• Thoughts?
