[BACKPORT 2.8][#13195] docdb: Increased retryable_request_timeout_sec…

…s to 660 seconds

Summary:
`retryable_request_timeout_secs` should be larger than YQL request timeout to avoid consistency issues like #537.
Separate `ysql_client_read_write_timeout_ms` flag was introduced for YSQL and by default it bumps up `YBClient` timeout to 600 seconds: 2294c84.
Hence we need to bump `retryable_request_timeout_secs` to a larger value.
