Remove `docs/` from packages?

[alexislefebvre]

Is your feature request related to a problem? Please describe.

When installing this dependency, the docs directory is included:

mkdir --parents /tmp/mcp-sdk/
cd /tmp/mcp-sdk/
composer require mcp/sdk
# …
ls vendor/mcp/sdk/docs/
client-communication.md  examples.md  mcp-elements.md  server-builder.md  transports.md

I think that these files are not necessary in this context.

Describe the solution you'd like

Add docs/ in https://github.com/modelcontextprotocol/php-sdk/blob/main/.gitattributes
