fix: Refactor component script and check if enum contents are numbers

[ErlingHauan]

Description

Functional changes

Previously, when generating JSON Schemas for the components, the script always asserted that enum values were strings.
Now, the script checks the first value of the enum and asserts the type (number or string) based on that.

In addition, the console now logs definitionName: ComponentNameExternal instead of definitionName: ComponentName for v4 components, because that is the actual definition we get the component schemas from.

Refactoring

• Used the expandRef utility function to get the external references to v4 components. This improves the quick fix from a couple of weeks ago.
• Moved the writeToFile function into a new file called fileUtils.ts.
• Moved many of the functions in run.ts into schemaUtils.ts and languageUtils.ts.

• Manual testing done (required)
• Relevant automated test added (if you find this hard, leave it and we'll help out)
