tidb-cloud: the TiDB Cloud Branching GitHub App link returns 404 #24570

Error Report

1. What is the URL/path of the document related to this issue?

The https://github.com/apps/tidb-cloud-branching link (TiDB Cloud Branching GitHub App) returns HTTP 404. It appears in the following files on both master and release-8.5:

• tidb-cloud/branch-github-integration.md: lines 14, 57, 61, 62, 63, 64, and 68
• tidb-cloud/releases/release-notes-2024.md: line 57

The weekly external URL check (#24545) already reports the 7 links in branch-github-integration.md. The link in release-notes-2024.md also fails linkChecker on any PR that touches that file, for example #24564.

2. How would you like to improve it?

Replace the link with the current location of the TiDB Cloud Branching GitHub App, or remove the link if the app is no longer public. The Japanese translation will follow the English fix through the weekly sync.
