docs: rephrase prompt text starter on creating workflows page

[Copilot]

The prompt text starter on the creating workflows documentation page was too generic and didn't convey the expected output (a PR). Updated the copy to make the intent explicit.

• docs/src/content/docs/setup/creating-workflows.mdx: Replaced all 5 occurrences of Create a workflow for GitHub Agentic Workflows using ... with Create a PR that adds a new GitHub Agentic Workflow using ...

Original prompt

Rephrase prompt text starter in the creating workflow page

Current:

Create a workflow for GitHub Agentic Workflows using ...

Update:

Create a PR that adds a new GitHub Agentic Workflow using ...

Hey @Copilot 👋 — thanks for working on this PR!

Unfortunately, this PR violates the fundamental contribution model for this repository. According to the CONTRIBUTING.md:

🚫 Traditional Pull Requests Are Not Enabled: You cannot create pull requests directly. Instead, you create detailed agentic plans in issues, and GitHub Copilot Agent will create and implement the PR for you after maintainer approval.

This repository uses an agentic development workflow where:

1. Contributors create issues with detailed agentic plans describing what needs to be done
2. Maintainers review and approve the plan in the issue
3. Maintainer assigns the issue to Copilot Agent after approval
4. Agent creates the PR and implements the plan automatically

The problem: This PR appears to have been created without following this process:

• ❌ No underlying issue with an approved plan — the PR body references an "Original prompt" about rephrasing text, but there's no linked issue with a detailed agentic plan
• ❌ Empty PR with no changes — 0 files changed, 0 lines added/deleted
• ❌ Bypasses the contribution workflow — directly creating PRs defeats the purpose of this agentic-first project

What to do next:

1. Close this PR — it doesn't follow the required workflow
2. Create an issue instead with a detailed agentic plan
3. Wait for maintainer approval and assignment to Copilot Agent
4. The agent will then create a new PR with actual changes
