Rename 'bun up' to 'bun db' (#141)

### Description

<!-- Provide a comprehensive description here about what your PR aims to
solve. -->

<!-- You may also add additional context -->

Update the "bun up" command to "bun db" since it's used to spin up a db
container. It's a better name. If we use "bun docs" to spin up a docs
server, we should use "bun db" to spin up a db server.
