update stubs from esptool.py v4.6.1

[igrr]

esptool.py v4.6.1 includes fixes for watchdogs:

• Super WDT (https://github.com/espressif/esptool/commit/80dc2104e163acddf6a6a6fa26c1e3f7068173c3)
• RTC WDT (https://github.com/espressif/esptool/commit/6fd91afec42f7717f02bb41a4bb2789c73187c63)

When a board that doesn't have any application flashed yet, there is nothing that will disable the watchdogs, therefore the stub has to correctly disable the watchdogs before flashing. These fixes should help when uploading large binaries, which currently may fail due to a watchdog timeout.

@brianignacio5 PTAL! If this looks okay, could we have a new bugfix release with this fix?
