[Security] Update repo roots to chromium roots (#42094)

The roots that we ship with gRPC have become extremely dated. See https://github.com/grpc/grpc/issues/37602 for more discussion.

This PR replaces them with the Chromium roots and updates the README to describe how to update them.

RELEASE NOTES:
* Update the fallback repo roots to the current Chromium trust store. These are the roots used if there are none configured by the user and there are none in the expected files on the system on which the gRPC process is running.

Closes #42094

gRPC – An RPC library and framework

gRPC is a modern, open source, high-performance remote procedure call (RPC) framework that can run anywhere. gRPC enables client and server applications to communicate transparently, and simplifies the building of connected systems.

To start using gRPC

To maximize usability, gRPC supports the standard method for adding dependencies to a user‘s chosen language (if there is one). In most languages, the gRPC runtime comes as a package available in a user’s language package manager.

For instructions on how to use the language-specific gRPC runtime for a project, please refer to these documents

  • C++: follow the instructions under the src/cpp directory
  • C#/.NET: NuGet packages Grpc.Net.Client, Grpc.AspNetCore.Server
  • Dart: pub package grpc
  • Go: go get google.golang.org/grpc
  • Java: Use JARs from Maven Central Repository
  • Kotlin: Use JARs from Maven Central Repository
  • Node: npm install @grpc/grpc-js
  • Objective-C: Add gRPC-ProtoRPC dependency to podspec
  • PHP: pecl install grpc
  • Python: pip install grpcio
  • Ruby: gem install grpc
  • WebJS: follow the grpc-web instructions

Per-language quickstart guides and tutorials can be found in the documentation section on the grpc.io website. Code examples are available in the examples directory.

Precompiled bleeding-edge package builds of gRPC master branch's HEAD are uploaded daily to packages.grpc.io.

To start developing gRPC

Contributions are welcome!

Please read How to contribute which will guide you through the entire workflow of how to build the source code, how to run the tests, and how to contribute changes to the gRPC codebase. For detailed C++ build instructions, see Building from source. The “How to contribute” document also contains info on how the contribution process works and contains best practices for creating contributions.

Troubleshooting

Sometimes things go wrong. Please check out the Troubleshooting guide if you are experiencing issues with gRPC.

Performance

See the Performance dashboard for performance numbers of master branch daily builds.

Concepts

See gRPC Concepts
