Bump @libsql/core dep in client-wasm to match pre-release

The version bump to 0.17.3-pre.1 left the wasm package's dependency
range at ^0.17.0, which does not match pre-releases. npm therefore
installed @libsql/core 0.17.2 from the registry into the subpackage's
node_modules instead of linking the workspace copy. The bundle script
then wipes node_modules before tsc runs, leaving the build unable to
resolve @libsql/core/*.
