Bump version to 2024.9.0-alpha.2

* move rate-limit-exceeded error reporting, earlier

a rate-limit-exceeded error has `kind:'client'`, so the branch that
adds the `Retry-After` would never get taken

(cherry picked from commit 8a982c61c01909e7540ff1be9f019df07c3f0624)

* Update Changelog

* fix

* indent
