Non-breaking change since people don't have to use the extra transformer argument.

Description

Reason for this change: I need to apply different content transformations depending on which file the data came from. Without knowing the file, the transformer function has to rely on brittle heuristics to identify the file based on its content (which can obviously change over time).

I think a new test case isn't needed for this but happy to provide one if someone thinks otherwise.

[NotWoods]

We still need a test case to make sure the correct path is being sent through. You can modify some of the existing tests to add that check.

@NotWoods Odd. If I run pnpm run test --filter ./packages/yaml locally, the tests are passing. Am I missing something?

[janosh]

Ah, different directory separators on UNIX ('/') and Windows ('\') is why it was failing.

[NotWoods]

Thanks!

@NotWoods you didn't use conventional commit on that merge. that'll hose our versioning and changelog generation. can you amend that commit and force push?

I was able to get it.

@NotWoods Can you say when this will be published?

[shellscape]

@janosh we typically make weekly publish rounds for plugins. we have a lot moving parts this week so don't be surprised if this takes until early next week to be seen on NPM. (We're not quite ready for automated publishing)
