Motivation:

Protobuf edition 2024 has been out for a little while now, we should
support it. Happily this is just a case of bumping the supported range.

Modifications:

- Widen the supported range
- Add an integration test

Result:

Users can generate gRPC code for protos which use `edition = "2024"`

Motivation

* `@main` references to `swiftlang/github-workflows` are deprecated.

Modifications

* Replace `@main` with `@0.0.7` in all workflow files.

Result

* Workflow files reference a pinned version of
`swiftlang/github-workflows`.

Motivation

* Following [GitHub's
announcement](https://github.blog/changelog/2025-09-19-deprecation-of-node-20-on-github-actions-runners/),
Node 20 is being deprecated and runners will begin using Node 24 by
default starting March 4th, 2026. Node 20 will reach end-of-life in
April 2026.

Modifications

* Upgrade GitHub Actions to their latest versions to ensure
compatibility with Node 24.
* Replace `actions/checkout@v4` with `actions/checkout@v6` in all
workflow files.

Result

* Workflow files reference `actions/checkout@v6`.

Motivation:

grpc-swift 2.3.0 updated the generated code to include the type of an
RPC. The expectations in some code gen tests in this package are now
incorrect.

Modifications:

- Bump the required version
- Update test expectation

Result:

Tests pass
