fix(sea): drop the unpublished sql-kernel optional dep (unblocks npm ci)

`@databricks/sql-kernel-linux-x64-gnu@0.1.0` is not published yet, so the
lockfile recorded it with no resolved version and `npm ci` rejected the
mismatch ("lock file's @databricks/sql-kernel-linux-x64-gnu@undefined does
not satisfy @0.1.0") — npm ci does NOT silently skip a pinned-but-
unresolvable optional dependency. Remove it from optionalDependencies until
the per-triple binding packages are actually published; the loader already
handles an absent binding (and version.test skips unless SEA_NATIVE_EXPECTED
is set). Re-add the optional deps once the `@databricks/sql-kernel-*`
packages ship.
