TEMP: default to ESP-IDF 6.1.0 for CI testing of Log V2

Sets recommended/latest/dev to 6.1.0, maps it to the pioarduino
prep_IDF6 platform branch, and points the PlatformIO framework source
at a pioarduino style repack of espressif v6.1 hosted at
bdraco/esp-idf, since pioarduino has not published 6.1 yet. The native
toolchain needs no hosting; esphome-libs/esp-idf already has v6.1.
Revert this commit and restore 5.5.5 before merge.
