Fix hasActionsWorkflows throwing an exception if the workflows folder doesn't exist

[mbg]

This problem was introduced in #3009 since lstatSync throws an exception by default if the filesystem object doesn't exist.

We likely didn't come across this because it requires both of the following conditions to hold:

• There is no .github/workflows folder
• And there is no input to languages

Pull Request Overview

This PR fixes a bug where the hasActionsWorkflows function would throw an exception when the .github/workflows folder doesn't exist. The fix uses the throwIfNoEntry: false option in fs.lstatSync to return undefined instead of throwing when the path doesn't exist.

• Updated fs.lstatSync to use { throwIfNoEntry: false } option to handle non-existent directories gracefully
• Added a test case to verify the function doesn't throw when the workflows folder is missing
