Consider posting the platform-specific for `grpc-tools` binaries to npm

[aelij]

Is your feature request related to a problem? Please describe.

grpc-tools uses node-pre-gyp to fetch platform-specific binaries at install time.
In build environments with an outbound-traffic allow-list this download phase fails, blocking CI/CD pipelines.

Environment

• Private build agents behind a strict firewall
• Only a few hosts (such as internal artifact feeds) are reachable

Current behaviour

.../node_modules/grpc-tools install: node-pre-gyp http GET https://node-precompiled-binaries.grpc.io/grpc-tools/v1.13.0/linux-x64.tar.gz
.../node_modules/grpc-tools install: node-pre-gyp ERR! install request to https://node-precompiled-binaries.grpc.io/grpc-tools/v1.13.0/linux-x64.tar.gz failed, reason: Client network socket disconnected before secure TLS connection was established 

Describe the solution you'd like

Could you provide an installation path that works without any additional endpoints? For example, ship the binaries in the package or as separate npm packages.
