Previously, diagnostic errors would display the filename and line number, along with "(source code not available)". This is because the
fmt
command directly loads and parses the configuration, instead of using the config loader.This commit registers the manually parsed source as a synthetic configuration file, so that the diagnostic formatter can look up the source for the range with the error and display it.
Fixes #20910
