Incorrect Update API Path

[tenaciousprevailer]

Spring Boot Version: 2.7.3 (Issue exists in 2.7.2, tried in that)
Elasticsearch Server Version: 8.1.2
The update path that spring data elastic search uses is:
POST /index/_doc/{docId}/_update
which gives error: no handler found for uri

Instead the path should be:
POST /index/_update/{docId}

Please fix this. I've to do a lot of workarounds to fix it.

Please provide a runnable code/ minimal project that demonstrates this error.

From org.springframework.data.elasticsearch.client.util.RequestConverters.update(UpdateRequest updateRequest)

Below is the code snippet.
public static Request update(UpdateRequest updateRequest) {
String endpoint = endpoint(updateRequest.index(), updateRequest.type(), updateRequest.id(), "_update");

This is causing the error, the endpoint generated is incorrect.
Refer the article on what the endpoint should be: https://www.elastic.co/guide/en/elasticsearch/reference/7.17/docs-update.html

Code FIX (Suggestion, Please review & test before accepting) :P:
String endpoint = endpoint(updateRequest.index(), "_update", updateRequest.id());

Seems no one else up to now used update with the reactive implementation, thanks for bringing this
up.

For the reactive client implementation up to version 4.4 we needed to copy code from the Elasticsearch library (it was still allowed at that time). This copied code was not adapted when in version 7 the type parameter was removed.
