Correct the Kubernetes example for Request Transformer Kong plugin

[anup-krai]

Where is the problem?

https://docs.konghq.com/hub/kong-inc/request-transformer/

What happened?

The Example plugin configuration given for Kubernetes in Request Transformer plugin is little incorrect -

Docs link - https://docs.konghq.com/hub/kong-inc/request-transformer/

Field names like remove, rename, add etc should not repeat in yaml for headers, querystring or body

Current example -

apiVersion: configuration.konghq.com/v1
kind: KongPlugin
metadata:
  name: request-transformer-example
config: 
  remove:
    headers:
    - x-toremove
    - x-another-one
  remove:
    querystring:
    - qs-old-name:qs-new-name
    - qs2-old-name:qs2-new-name
  remove:
    body:
    - formparam-toremove
    - formparam-another-one
  replace:
    body:
    - body-param1:new-value-1
    - body-param2:new-value-2
  rename:
    headers:
    - header-old-name:header-new-name
    - another-old-name:another-new-name
  rename:
    querystring:
    - qs-old-name:qs-new-name
    - qs2-old-name:qs2-new-name
  rename:
    body:
    - param-old:param-new
    - param2-old:param2-new
  add:
    headers:
    - x-new-header:value
    - x-another-header:something
  add:
    querystring:
    - new-param:some_value
    - another-param:some_value
  add:
    body:
    - new-form-param:some_value
    - another-form-param:some_value
plugin: request-transformer

Expected example -

apiVersion: configuration.konghq.com/v1
kind: KongPlugin
metadata:
  name: request-transformer-example
config: 
  remove:
    headers:
    - x-toremove
    - x-another-one
    querystring:
    - qs-old-name:qs-new-name
    - qs2-old-name:qs2-new-name
    body:
    - formparam-toremove
    - formparam-another-one
  replace:
    body:
    - body-param1:new-value-1
    - body-param2:new-value-2
  rename:
    headers:
    - header-old-name:header-new-name
    - another-old-name:another-new-name
    querystring:
    - qs-old-name:qs-new-name
    - qs2-old-name:qs2-new-name
    body:
    - param-old:param-new
    - param2-old:param2-new
  add:
    headers:
    - x-new-header:value
    - x-another-header:something
    querystring:
    - new-param:some_value
    - another-param:some_value
    body:
    - new-form-param:some_value
    - another-form-param:some_value
plugin: request-transformer

Please let me know where can I update this change. I am not able to find it as these are picked from value_in_examples field under config.

What did you expect to happen?

The Kubernetes example needs to be corrected for this plugin.

Hey, the ability to do this was added in this PR https://github.com/Kong/docs.konghq.com/pull/4493/files

I can provide an example of what the syntax would look like tomorrow if you still want to tackle this task.
