how audio-recorder link esp-timer when idf-version < 5.0 (AUD-4602)

[IamFive]

audio-recorder component only requires esp-timer when idf-version >= 5.0. but why the code uses esp-timer directly, how it links when compile.

dear @IamFive , before idf v5.0, esp_timer is automatic added to the components requirements, so there is no need to append to COMPONENT_REQUIRES list. Compile can be sucess when build with IDF v4.4

thank you.
