[shannonlal]

Adding Postman server to the community servers list.

Description

Adding Postman to the community servers list in README.md. This server provides Postman API testing through the Newman runner.

Server Details

• Server: Postman
• Changes to: README.md (adding new community server)

Motivation and Context

Postman is a popular API Testing framework that allows for quick testing and validation of APIs for developers. Under the hood it combines Postman and Newman (A Postman collection runner) that enables developers to build collections and then use for integration testing. Adding it to the community servers list will help users discover and utilize Postman functionality in their API Development. The server provides:

• The ability to run Postman collections
• The ability to get the test results back from these collections
• Can create and update Postman Colletions

How Has This Been Tested?

Tested with Claude in Cline (VS Code):

• Create Postman Collections
• Run the Postman Collections
• Verify the responses from the collections with newman

@jspahrsummers ok. I had done a rebase and accept the changes. I will try a merge instead see if that works

[shannonlal]

@jspahrsummers I think I will close this PR and open a new one and do a merge it will be eaiser
