Subject: [PATCH] Report BAT_CONFIG_DIR in bat --diagnostic

BAT_CONFIG_DIR overrides the config directory (src/bin/bat/directories.rs) and is documented in the README, but it was missing from the environment list that bat --diagnostic prints, so a bug report never showed where bat was actually reading its config from. Extend diagnostic_sanity_check to cover it.
