Pursuant to https://github.com/elastic/elasticsearch/pull/123928 created by @DaveCTurner: - [ ] Update the all the links in [server/src/main/resources/org/elasticsearch/common/reference-docs-links.txt](https://github.com/elastic/elasticsearch/blob/main/server/src/main/resources/org/elasticsearch/common/reference-docs-links.txt) to reflect the new URL paths for those pages post-docs migration. - [ ] Update the base URL from the old [https://www.elastic.co/guide/en/elasticsearch/reference/${MAJOR}.${MINOR}/](https://www.elastic.co/guide/en/elasticsearch/reference/$%7BMAJOR%7D.$%7BMINOR%7D/) once the new base URL is confirmed These links are emitted by Elasticsearch in various ways (typically logs and error responses) and need to be valid permalinks. > [!WARNING] > The `@UpdateForV9` marker essentially makes this a blocker for the 9.0 release.
