chore(deps): bump actions/github-script from 8 to 9

[dependabot]

Bumps actions/github-script from 8 to 9.

Release notes

Sourced from actions/github-script's releases.

v9.0.0

New features:

• getOctokit factory function — Available directly in the script context. Create additional authenticated Octokit clients with different tokens for multi-token workflows, GitHub App tokens, and cross-org access. See Creating additional clients with getOctokit for details and examples.
• Orchestration ID in user-agent — The ACTIONS_ORCHESTRATION_ID environment variable is automatically appended to the user-agent string for request tracing.

Breaking changes:

• require('@actions/github') no longer works in scripts. The upgrade to @actions/github v9 (ESM-only) means require('@actions/github') will fail at runtime. If you previously used patterns like const { getOctokit } = require('@actions/github') to create secondary clients, use the new injected getOctokit function instead — it's available directly in the script context with no imports needed.
• getOctokit is now an injected function parameter. Scripts that declare const getOctokit = ... or let getOctokit = ... will get a SyntaxError because JavaScript does not allow const/let redeclaration of function parameters. Use the injected getOctokit directly, or use var getOctokit = ... if you need to redeclare it.
• If your script accesses other @actions/github internals beyond the standard github/octokit client, you may need to update those references for v9 compatibility.

What's Changed

• Add ACTIONS_ORCHESTRATION_ID to user-agent string by @​Copilot in actions/github-script#695
• ci: use deployment: false for integration test environments by @​salmanmkc in actions/github-script#712
• feat!: add getOctokit to script context, upgrade @​actions/github v9, @​octokit/core v7, and related packages by @​salmanmkc in actions/github-script#700

New Contributors

• @​Copilot made their first contribution in actions/github-script#695
