build: clean up redundant exclude field from tsconfig-build.json

The exclude field has been removed from `tsconfig-build.json` as it is redundant. This configuration is used by Bazel, which already specifies the input files explicitly, making the exclude field unnecessary. This change simplifies the configuration without impacting the build process.
