Only read packages from action.yml that specifies version

Took a stab at fixing #690 by only parsing action.yml version if version exists.

Closes #690

PR Summary

• Enhanced Condition in Virtual Environment Utilization
  We've introduced a new condition in our environment setup process. This simply means we now have an improved way to include certain tools if specific conditions are met. This promises more flexibility in our deployment and architectural setup.

• Added new test
  A new file named action.yml has been added to our test folder 'no-version'. This file will be instrumental in running certain test cases ensuring our application's ongoing stability and efficiency.

• Additional Test Case
  An additional test case was included within our functional development environment test suite. It is designed to evaluate the processing of packages. Simply, this ensures on how well our application handles data packages even when they might not perfectly conform to expected formatting. This further improves our application stability and error-handling ability.

• A second test case was added to the same file to test the tolerant parsing of .node-version details. This helps the application to handle discrepancies or issues while reading Node.js version information from the configuration file.

The summary is a cool feature, but it looks like it's off by one because this seems like it thinks #L167 is part of this change when it isn't. Oh well, off by one errors are one of the two hardest problems in computing after all :)
