Build full package in Dockerfile to include all commands

[SamMorrowDrums]

What

Update Dockerfile to build the full ./cmd/github-mcp-server package instead of just main.go.

Why

The current Dockerfile only builds main.go:

go build ... -o /bin/github-mcp-server cmd/github-mcp-server/main.go

This excludes other command files like list_scopes.go, generate_docs.go, etc. As a result, the Docker image is missing commands like list-scopes which is useful for determining required OAuth scopes.

Change

- -o /bin/github-mcp-server cmd/github-mcp-server/main.go
+ -o /bin/github-mcp-server ./cmd/github-mcp-server

Testing

# Before: missing list-scopes command
docker run --rm ghcr.io/github/github-mcp-server:test list-scopes --help
# Error: unknown command "list-scopes" for "server"

# After: works
docker run --rm ghcr.io/github/github-mcp-server:test list-scopes --toolsets=repos,issues --output=summary
# Required OAuth scopes for enabled tools:
#   read:org
#   repo
# Total: 2 unique scope(s)

cc @JoannaaKL - this enables the list-scopes command in the Docker image, which you mentioned wanting for another tool as well.

Pull request overview

This PR fixes the Dockerfile build command to include all Go files in the cmd/github-mcp-server package, not just main.go. This ensures commands like list-scopes and generate-docs are available in the Docker image. Additionally, the PR simplifies the script/licenses script to use a consistent version across CI and local environments.

Changes:

• Updated Dockerfile to build the full package path (./cmd/github-mcp-server) instead of just the main.go file
• Simplified script/licenses to use go-licenses v2 module path with pinned version for both CI and local development
