Migrate content where only parent info.json exists

[zvecr]

Description

Keyboards discovered with the following...

# asdf/info.json
# asdf/rev1/rules.mk
# asdf/rev2/rules.mk
for kb in $(qmk list-keyboards); do
    if [[ -f keyboards/${kb}/rules.mk && ! -f keyboards/${kb}/info.json ]]; then
        if [[ -f keyboards/${kb}/rules.mk && ! -s keyboards/${kb}/rules.mk ]]; then
            true
        elif grep -q "intentionally left blank" keyboards/${kb}/rules.mk; then
            true
        else
            echo "TODO: keyboards/${kb}/rules.mk"
            # cat keyboards/${kb}/rules.mk
        fi
    fi
done

Candidates flagged as TODO are those that can not easily be migrated for #22891.

[lesshonor]

All SHAs except those for the bpiphany/frosty_flake keymaps match against 548983a, either without any changes or when the changes to features are replicated.

Matched full stop:
canary/canary60rgb/v1
mechwild/sugarglider/*
melgeek/mojo68
melgeek/mojo75
melgeek/tegic
melgeek/z70ultra

Matched after feature changes were replicated:
handwired/qc60/proto - enabled bootmagic and mousekeys
handwired/stef9998/split_5x7/rev1 - enabled bootmagic, disabled command
murcielago/rev1:default - enabled bootmagic
polilla/rev1 - enabled bootmagic and mousekeys
spacetime/rev1 - enabled bootmagic, disabled console
spacetime/rev2 - enabled bootmagic, disabled console
xiudi/xd004/v1 - enabled space cadet

Aside from enabling bootmagic, I'm going to assume the mismatch is because both Frosty Flake keyboards currently write one wrong LED high during pre-init (oops) and call it there.
