[Feature] Updates CLI flags for `leo build` and `leo run`

[alex-aleo]

🚀 Feature

Currently there are a number of flags in the Leo CLI for leo build that are either ambiguous or don't seem to serve much of a purpose.

Ambiguous:

--offline
    Enables offline mode.
--no-cache
    Don't use the dependency cache.
--no-local
    Don't use the local source code.

Do these matter for leo build?:

--private-key <PRIVATE_KEY>
    The private key to use for the deployment. Overrides the `PRIVATE_KEY` environment variable.
--network <NETWORK>
    The network to deploy to. Overrides the `NETWORK` environment variable.
--endpoint <ENDPOINT>
    The endpoint to deploy to. Overrides the `ENDPOINT` environment variable.
--devnet
    Whether the network is a devnet. If not set, defaults to the `DEVNET` environment variable.
--consensus-heights <CONSENSUS_HEIGHTS>
    Optional consensus heights to use. This should only be set if you are using a custom devnet.

Update: looking at #28768 (comment) , why do build and run need to have network calls at all? For pulling dependencies?
