Explain missing nodeJS error better (v2)

[1000TurquoisePogs]

If you configure "node.home" wrong, you will likely encounter

• Output:
  node: read_yaml 10: /zowe-release-2.18.0/bin/commands/init/certificate/index.sh 20: .: zwecli_process_command 4: /zowe-release-2.18.0/bin/zwe 98: FSUM7351 not found
  Error ZWEL0157E: Zowe dataset prefix (zowe.setup.dataset.prefix) is not defined in Zowe YAML configuration file.

This has time and time again caused people to believe the problem is "zowe.setup.dataset.prefix" when it isnt.

With this change, it will now print:

Error ZWEL0319E: NodeJS required but not found. Errors such as ZWEL0157E may occur as a result.
The value 'node.home' in the Zowe YAML is not correct. Set it to the parent directory of 'bin/node'."
For example, if NodeJS is at '/opt/nodejs/bin/node', then set 'node.home' to '/opt/nodejs'.

• Output:
  node: read_yaml 10: /zowe-release-2.18.0/bin/commands/init/certificate/index.sh 20: .: zwecli_process_command 4: /zowe-release-2.18.0/bin/zwe 98: FSUM7351 not found

Error ZWEL0157E: Zowe dataset prefix (zowe.setup.dataset.prefix) is not defined in Zowe YAML configuration file.

ZWEL0157E still is printed, because of how this read_yaml function is called, doing an exit wont stop execution. So, the first message at least warns about the second.

Fixes #3426 for v2
