Fix OTA manifest lambda for ESPHome dev

[bharvey88]

Version: 26.10.12.1

What does this implement/fix?

Fixes the build against ESPHome dev. esphome#19211 changed the http_request update entity's set_source_url() to take a const char * and keep the pointer, so passing a std::string fails with cannot convert 'std::string' to 'const char*'.

apply_ota_source now picks between the two manifest URLs as string literals, which stay valid for the life of the firmware. Current stable still accepts this, since its const std::string & parameter converts from const char *. No change in behavior.
