fix(dlt): always use destination_client for connection config

The dlt destination-client selection gated the 1.10.0 API change with a
string comparison (`dlt.__version__ >= "1.10.0"`). String comparison is
lexicographic, so it wrongly evaluated "1.9.0" >= "1.10.0" (and "1.2.0",
"1.5.10", ...) as True, sending every 1.x version down the >=1.10.0
branch.

`destination_client()` is the public accessor on every realistically
supported dlt version, and the pre-1.10 `_sql_job_client` fallback was
already unreachable because of the same string-compare bug, so drop the
version gate and always use `destination_client()`.
