examples/pre_encrypted_ota: readme tweaks and link to component manager
# Encrypted Binary OTA
-This example demonstrates OTA updates with pre-encrypted binary using `esp_encrypted_img` component's APIs and tool. Pre encrypted firmware binary must be hosted on OTA update server. This firmware will be fetched and then decrypted on device before being flashed. This allows firmware to remain `confidential` on the OTA update channel irrespective of underlying transport (e.g., non-TLS).
