Bump default GitHub MCP Server to v1.5.0 and MCP Gateway to v0.3.31

[Copilot]

This updates the two pinned MCP container defaults called out in the CLI version update issue: GitHub MCP Server v1.4.0 → v1.5.0 and MCP Gateway v0.3.30 → v0.3.31. The generated workflow artifacts and embedded pin data are refreshed so compiled workflows consistently reference the new versions and digests.

• Default version updates

  • Updated /home/runner/work/gh-aw/gh-aw/pkg/constants/version_constants.go:
    • DefaultGitHubMCPServerVersion = "v1.5.0"
    • DefaultMCPGatewayVersion = "v0.3.31"

• Compiled workflow refresh

  • Regenerated all workflow lockfiles so emitted workflow YAML now references the new MCP images.
  • Refreshed the workflow manifests and download steps to use the new pinned container refs.

• Container pin cache sync

  • Updated .github/aw/actions-lock.json and synced embedded action/container pin data:
    • pkg/actionpins/data/action_pins.json
    • pkg/workflow/data/action_pins.json
  • Added the new GHCR digests for gh-aw-mcpg:v0.3.31 and github-mcp-server:v1.5.0.
  • Removed superseded cache entries for the previous default versions.

• Golden fixture updates

  • Updated the WASM golden fixtures that snapshot compiled output so they match the new default MCP image references.

const DefaultGitHubMCPServerVersion Version = "v1.5.0"
const DefaultMCPGatewayVersion Version = "v0.3.31"

Pull request overview

This pull request bumps the default pinned container versions for the GitHub MCP Server and MCP Gateway used by gh-aw, and refreshes generated artifacts so compiled workflows consistently reference the updated image tags and digests.

Changes:

• Updated the default versions in pkg/constants/version_constants.go to GitHub MCP Server v1.5.0 and MCP Gateway v0.3.31.
• Regenerated workflow lockfiles and WASM golden fixtures so emitted workflow YAML references the new container images.
• Synced container pin caches (.github/aw/actions-lock.json, pkg/*/data/action_pins.json) to add the new digests and drop the superseded ones.
