`TypeError` calling `Traversable.read_text()` via `importlib.resources`

[zooba]

Bug report

importlib.resources.abc.Traversable.read_text has a signature that only takes an encoding parameter.

importlib.resources._functional.read_text calls it passing errors.

This, unsurprisingly, causes a TypeError. My exact error message is Traversable.read_text() got an unexpected keyword argument 'errors', but I believe it's an instance of CompatibilityFiles.SpecPath (as I've never bothered updating this code for the structural changes).
