docs: add working-directory navigation example to side-repo-ops pattern

[Copilot]

current: true is commonly misread as "make this the cwd" — it only injects a hint into the agent's system prompt and has no effect on the actual working directory. Without an explicit cd in the prompt, the agent starts in $GITHUB_WORKSPACE (the side repo root) and must infer the correct path.

Changes

• patterns/side-repo-ops.mdx — adds a new "Checking Out the Target Repository" subsection under Advanced Topics with a concrete end-to-end example combining checkout.current: true + path: repo and the required cd prompt instruction:

checkout:
  - repository: ${{ github.event.inputs.target_repo }}
    path: repo
    github-token: ${{ secrets.GH_AW_MAIN_REPO_TOKEN }}
    current: true

Navigate into the folder where the target repository has been checked out into: cd ${{ github.workspace }}/repo

• reference/checkout.md — adds an [!IMPORTANT] callout after the current: true code example clarifying the working-directory behaviour and showing the required cd pattern inline.

Pull request overview

Clarifies that checkout.current: true does not change the agent’s working directory, and provides explicit cd guidance to prevent agents from running local tools in the wrong repo.

Changes:

• Add an [!IMPORTANT] callout to the current: true reference clarifying working-directory behavior and the need for an explicit cd.
• Add an “Advanced Topics” example to the SideRepoOps pattern showing end-to-end checkout-to-path + current: true + cd prompt instruction.

The phrase "has been checked out into" is ungrammatical (double “into”) and may read awkwardly in the example prompt. Consider rephrasing to something like "checked out to" / "checked out at" / "checked out in" (e.g., "Navigate to the checked-out repository: cd …").

Suggested change

	> Navigate into the folder where the target repository has been checked out into: cd ${{ github.workspace }}/target
	> Navigate to the checked-out target repository: cd ${{ github.workspace }}/target

The sentence "has been checked out into" reads awkwardly (double “into”). Rephrase the instruction to something like "Navigate to the checked-out repository: cd …" or "Navigate into the checked-out repository directory: cd …".

Suggested change

	Navigate into the folder where the target repository has been checked out into: cd ${{ github.workspace }}/repo
	Navigate to the checked-out repository: cd ${{ github.workspace }}/repo
