Describe the bug

I'm able to search and find the GitHub OpenAPI description and select the endpoints I care about, which are:

• /repos/{owner}/{repo}#GET
• /repos/{owner}/{repo}#PATCH
• /repos/{owner}/{repo}#DELETE

When trying to generate an "API Plugin" for the above endpoints, I got the following error:

In the output folder, both generated files (plugin and sliced openapi) are wrong.
Plugin file has no functions nor runtimes objects.

{
  "schema_version": "v2",
  "name_for_human": "GitHub v3 REST API",
  "description_for_human": "GitHub\u0026apos;s v3 REST API.",
  "description_for_model": "GitHub\u0026apos;s v3 REST API.",
  "logo_url": "https://api.apis.guru/v2/cache/logo/https_twitter.com_github_profile_image.jpeg",
  "namespace": "githubrepo",
  "capabilities": {
    "localization": {}
  }
}

The sliced OpenAPI description has no "paths".

Using the same extension version I'm able to correctly generate an API Plugin for other GitHub endpoints, like /search node.
Also, after getting the above error, I'm not able to load a new OpenAPI description. For that, I need to close and reopen VS Code.

Expected behavior

I should be able to generate an API plugin with functions and runtime for the selected endpoints as well as have a sliced OpenAPI description with only the selected endpoints in the paths

How to reproduce

Just try to generate a plugin for all the following endpoints:

• /repos/{owner}/{repo}#GET
• /repos/{owner}/{repo}#PATCH
• /repos/{owner}/{repo}#DELETE

Looks like the extension shows/sends /repos/{org-id}/{repo-id}#GET as the include pattern while the openapi description has the path as /repos/{owner}/{repo}#GET(this is due to the path deduplication logic by kiota).

Authored #4722 to resolve the issue with the indexer cleanup logic that doesn't add a wildcard for the last indexer.

@andrueastman will this fix the extension showing the wrong path?

FYI @ElinorW

[andrueastman]

The extension will show the deduplicated paths /repos/{org-id}/{repo-id} this is because the document has some paths as
/repos/{owner}/{repo} and others as /repos/{template_owner}/{template_repo}. So Kiota will deduplicate them to avoid having multiple branches as that is ambiguous from an openaApi standpoint.

This is similar to the scenario to the test at
