fix: check docker engine is prior to linting and give a useful error …

…when it is not (#1506)

## Description:
Runs `docker version` prior to linting, to verify that docker engine is
up. Throws an exception with a suitable error message if docker is down.

The error is still a thrown stacktrace but now the message is correct.
Looks like this:

```
?1 kurtosis % ./cli/cli/scripts/launch-cli.sh lint --cli-log-level debug
INFO[2023-10-10T14:05:56+01:00] This depends on 'pyfound/black:23.9.1'; first run may take a while as we might have to download it
Error:  An error occurred running command 'lint'
 --- at ...kurtosis/kurtosis/cli/cli/command_framework/lowlevel/lowlevel_kurtosis_command.go:301 (LowlevelKurtosisCommand.MustGetCobraCommand.func2) ---
Caused by: An error occurred checking Docker version. Please ensure Docker engine is running and try again.
 --- at ...kurtosis/kurtosis/cli/cli/commands/lint/lint.go:102 (run) ---
Caused by: exit status 1
```
