README: remove the section on switching from config folder copies

The printer now runs from the repo, so the one-time migration notes are
no longer needed.

-### Switching from copies in the config folder
-
-If these macros already exist as files in your config folder (as on the
-original printer: `Macros/*.cfg` and `bd_pa_afc_spoolman.cfg`), remove those
-includes when adding `klipper-macros.cfg`, otherwise the macros are defined
-twice and the old copy may win:
-
-- remove `[include bd_pa_afc_spoolman.cfg]` and
-  `[include ./blobifier/blobifier.cfg]` from `printer.cfg`,
-- remove `[include ./Macros/macros.cfg]` and add
-  `[include klipper-macros/klipper-macros.cfg]` after `[include AFC/*.cfg]`,
-- keep including what is not in this repo yourself, for example
-  `[include Macros/timelapse.cfg]` and `[include Macros/TEST_SPEED.cfg]`.
-
-`bd_pa_variables.cfg` (saved PA values and the Blobifier blob count) stays
-where it is, in the config folder; it is data, not part of the repo. Before,
-both `blobifier.cfg` and `bd_pa_afc_spoolman.cfg` had their own
-`[save_variables]`; Klipper merged them and the last one won, so the blob
-count was already stored in `bd_pa_variables.cfg` and
-`blobifier/blob_vars.cfg` was no longer used. Now it is defined once, in
-`save_variables.cfg`.
