Add instructions to run via REPL

Suggested changes to docs following discussion in CliMA/ClimaAtmos.jl#4125.

@szy21 julia --project=.buildkite .buildkite/ci_driver.jl --config_file path_to_mysim.yml fails as in #4125 when run without explicit reference to the appropriate common config. Do you think we should add a link here in the docs to the common configs docs page, or provide a more explicit example?

Let's add a link to the common configs docs. The config/common_configs/numerics_column_ze63.yml is not needed if you set the numerics config correctly in path_to_mysim.yml. And it's likely users want to have their own numercis config.
