e2e tests for s3,snowflake,supabase and ethereum

[supergi0]

1. Modified CI to use cached Dozer folder incase of same Cargo.toml.
2. CI split into build and test jobs.
   • build job: builds and uploads the dozer binary as an artifact.
   • test job: tests the config files via pnpm test.
3. Increased retry frequency to 1000ms and retires to 100, for snowflake and supabase.
4. added --exit to stop operations once the mocha tests give output, refer here. This is likely due to dozer connections(snowflake, aws etc..) not getting properly cleaned up, but isn't worth exploring since we already get our outputs.
5. Change mocha test timeout to 60 sec instead of 30 sec default to accommodate snowflake connection.

Will definitely need squash and merge :)
