chore: Removed server url from start-https command in ClientSetup (#21957)

## Description

In the Client Setup Document section for [Create local HTTPS
certificates](https://github.com/appsmithorg/appsmith/blob/release/contributions/ClientSetup.md#if-you-would-like-to-hit-a-different-appsmith-server),
removed the URL https://release.app.appsmith.com/ from the command
./start-https.sh as this step is already mentioned in the section [If
you would like to hit a different Appsmith
server](https://github.com/appsmithorg/appsmith/blob/release/contributions/ClientSetup.md#if-you-would-like-to-hit-a-different-appsmith-server)
