Pull Request Overview

This PR adds documentation for the dedup feature specifically for Golang applications, replacing the previous multi-language documentation. The documentation has been streamlined to focus on Go-specific implementation and usage patterns.

Key changes:

• Replaces Node.js, Java, and Python dedup documentation with Golang-specific instructions
• Updates command examples to use the newer keploy test command with --dedup flag
• Simplifies the workflow by removing language-specific middleware setup in favor of Go SDK import

There's a spelling error in 'Pre-requsite'. It should be 'Pre-requisite'.

Suggested change

	**1. Pre-requsite**
	**1. Pre-requisite**

[Copilot]

There's a duplicate word 'the the' which should be 'the following'.

Suggested change

	Add the the following on top of your main application file : -
	Add the following on top of your main application file : -

[Copilot]

The sentence is incomplete and lacks proper punctuation. It should end with a period and could benefit from more context about what the dedupData.yaml file contains or its purpose.

Suggested change

	After this Run
	This will generate a dedupData.yaml file, which contains metadata and coverage information for each test case. This file is used in the next step to identify and remove duplicate tests.

This is confusing. Club this with the above, like for native and for docker.
