docs(README): prune outdated servers

[Chesars]

Description

Cleaned up the server list by removing outdated repositories from the Readme.

Motivation and Context

issue: Some repositories are no longer maintained but still appear in the Community section.
solution: keep repositories maintained by contributors and official teams.
This change is necessary because some community repositories are no longer maintained but still appear in the Community section; on the other hand, official repositories, often maintained by the same contributors, are available.

Types of changes

• Bug fix (non-breaking change which fixes an issue)
• New feature (non-breaking change which adds functionality)
• Breaking change (fix or feature that would cause existing functionality to change)
• Documentation update

Checklist

• New and existing tests pass locally

Fixes #2633
