client/container: bash: add hledger aliases

The original intent of the `ledger` facade was to describe a general
purpose "ledger" command abstraction; not specifically the `ledger`
software (predecessor to hledger) nor the `ledger` hardware device.

As `hledger` is currently the exclusive internal "ledger" component,
adding `hledger` as an alias seems to be an appropriate-enough addition
that won't break existing abstraction/functionality.
