Docker: Usable snapshot import args

Context

In a docker environment, it's possible to pass arguments after the command octez-snapshot-import to the container but it fails due to arguments being misplaced in the executing command.

octez-node: required COMMAND name is missing, must be one of 'export', 'import' or 'info'

This update aims to fix the order in the command.

Some use cases are:

• --no-check option to improve snapshot import speed;
• --block <block_hash> option to specify the expected head block in the snapshot to ensure snapshot integrity.

Manually testing the MR

To test: run a snapshot import in a docker container using the command octez-snapshot-import --no-check --block <block_hash>
