Failing to fmt for official example

[kachick]

#8

Error formatting /home/kachick/repos/github.com/kachick/dprint-plugin-kdl/example/official.expected.kdl. Message: Formatting succeeded initially, but failed when ensuring a stable format. This is most likely a bug in the plugin where the text it produces is not syntatically correct. Please report this as a bug to the plugin that formatted this file.

Expected valid node terminator.
Had 1 error formatting.

Might be fixed in kdl-org/kdl-rs#77

After #83, it is reversible now. So I removed the known issue files even if layout is not ideal state.
