[Custom Functions] when importing CommonJS modules, lint does not work if you do not add `.js` in `require`

[formulahendry]

Describe the bug
When importing CommonJS modules, lint does not work if you do not add .js in require

To Reproduce

1. Git clone from https://github.com/formulahendry/test
2. Install vscode-spectral extension
3. Open test-spectral\openapi.yaml file

Actual behavior
Lint does not show any error.

Expected behavior
Lint should show error message for message: aaa222: https://github.com/formulahendry/test/blob/91ea37278d2e316a74f016b06dea2b08f80e6bcb/test-spectral/openapi.yaml#L5

However,

If you run from CLI with the same rule: spectral lint .\test-spectral\openapi.yaml --ruleset .\test-spectral\test_rules\my-ruleset.yaml
Lint works!

In test-spectral\test_rules\functions\abc.js, if you add a .js in require: var { getMessages } = require("../function_utils/test.js");
Lint works!

the .js file extension should be optional when importing CommonJS modules.

Screenshots

Environment:

• Extension version: 1.1.2
• VS Code version: 1.86
• Operating System: Windows 11

Additional context
.js should be optional in require:

Same issue here for macos ...

It's not possible for me to update all the references to include the .js as the original ruleset is written in typescript and transpiled to JS.
