Many broken URLs in the documentation pointing to spring reference with #hash part

For example here there are several links referencing to spring reference documentation:

• broker prefix which is correctly redirects to new location but losing hash part if the URL in the process. The correct new URL should be: https://docs.spring.io/spring/docs/current/spring-framework-reference/web.html#websocket-stomp

• Flow of Messages redirects to new location, but should redirect here (note the hash part).

Initially I wanted to just fix these URLs at least in webscoket docs and create a pull request, but then I began to have doubts: maybe there is some mechanism already to bulk-update all URLs from old to new locations? Or maybe you want to make this update centralized and don't want to accept a bunch of pull requests from different people fixing these broken URLs here and there...

Let me know if I should make a PR to fix at least some URLs or you consider another approach (some script?) to fix this all at once.

Start with docs/manual/src/docs/asciidoc/_includes/servlet/integrations/websocket.adoc and inspect the documented links to the Spring reference. Determine whether the broken hash links are isolated or require a bulk update across the documentation, then verify that corrected URLs retain their section anchors.
