pkg/generator: use the qualified ref filename so it can be found

[mgabeler-lee-6rs]

When generating types for a set of schemas with deeply nested refs across several subdirectories, it can fail due to not joining the parent file's base path (directory).

The properly qualified path was already computed, just need to use it!

@mgabeler-lee-6rs can you please provide some examples and/or testcases here?

[mgabeler-lee-6rs]

I'll dig up something proper, but the rough issue IIRC is with $Ref pointing at a local file in a subdirectory

[mgabeler-lee-6rs]

@omissis I was able to narrow down my production case that broke on this to a fairly minimal reproducer as a test case. You can cherry-pick the test over to main and see how it fails. It's a bit of an uncommon scenario, using a $ref and overriding some things (e.g. description).

While paths are involved, it doesn't require the $ref to point to a subdir, it only requires the tool to not be run in the same folder as the schema, which is the way the tests already run 🙂

I will take a look, thanks @mgabeler-lee-6rs
