We currently throw two different errors into a similar-but-different
error code:
- Errors when trying to lock the reftable stack.
- Errors when trying to write to the reftable stack which has been
modified concurrently.
This results in unclear error handling and user-visible error messages.
Create a new `REFTABLE_OUTDATED_ERROR` so that those error conditions
can be clearly told apart from each other. Adjust users of the old
`REFTABLE_LOCK_ERROR` to use the new error code as required.
