[APIM-4.2.0] Configure WSO2 IS as a Key Manager Page needs improvements

Location: https://apim.docs.wso2.com/en/4.2.0/administer/key-managers/configure-wso2is-connector/

• In the first point of Step 1 in [1] should be changed to the latest IS version.

  ~~WSO2 Identity Server 5.11.0~~ >> WSO2 Identity Server 6.0.0
  

• In the 4th point jar versions should be changed in [1]. (This worked for me after I took the latest jars from the APIM pack) - related issue: https://github.com/wso2/product-apim/issues/12625

  wso2is.key.manager.core and wso2is.notification.event.handlers
  

• The screenshot needs to be updated in the 4th point in [2] ( required fields are there, but clearly identify that the screenshot is from older APIM)

• Issuer, Token Endpoint, Revoke Endpoint, Userinfo Endpoint, and Scope Management Endpoint must be changed as mandatory in the 5th point in [2]

Open the configure WSO2 IS connector page and review Step 1 and Step 2, using the linked related issue for the jar-version context. Update the IS version, jar references, screenshot, and required endpoint fields described in the issue; done means the page reflects the current APIM and IS setup.
