README: rauc-conf needs to be appended now instead of rauc

With d51bab8 (rauc: split package into 'rauc' for binary and 'rauc-conf' for configuration), users need to append rauc-conf instead of rauc when providing their device-specific configuration. This was not reflected by the docs yet. Also add an explicit migration note early in the README.rst. Signed-off-by: Enrico Jörns <[email protected]>

+Migration Notes
+===============
+
+Since **scarthgap**, the platform configuration (system.conf, keyring, etc.) was
+moved to a separate ``rauc-conf.bb`` recipe to allow building the rauc package
+with ``TUNE_PKGARCH`` and have a clearer separation between the binary and the
+configuration.
+
+Thus when updating to scarthgap or newer, make sure to move all
+configuration-specific adaptions from your ``rauc_%.bbappend`` to a
+``rauc-conf.bbappend`` file.
