## Improve CLI --help Output with Command Descriptions

### Description

I’d like to suggest an improvement to the CLI `--help` output for drizzle-kit. Currently, the commands do not include descriptions, making it slightly challenging to understand the functionality at a glance. Adding brief descriptions would significantly enhance usability by providing immediate context.

As someone new to ORMs, I found it challenging to understand commands like `push` and `migrate` just from their names. While `studio` is intuitive, a short explanation in the `--help` output would make it much easier to grasp their purpose without needing to search elsewhere.

### Proposal

Add one-line descriptions to each drizzle-kit command in the `--help` output.
Ensure that common commands like push and migrate are clearly explained.

## Contribution

I’d be happy to work on this if the change is welcome. Just wanted to check in first to see if this is something you'd be open to.
