[ESP32] "hwcrypto/sha.h" has been moved

[kvoit]

After updating my espressif32 platform in PlatformIO from 3.2 to 4.2,
"hwcrypto/sha.h" cannot be included in Websockets.cpp anymore.

Issue #3245 in esp-idf states that this library has been moved, and changing the include accordingly fixes this issue.

Steps to reproduce the behavior:

1. Try to use RemoteDebug with espressif32 platform 4.2

Expected behavior
It should work and not throw include errors.

Arduino Information:

• OS: Ubuntu 22.04
• IDE VSCode w/ PlatformIO
• ESP32, espressif 4.2
