Fixed README: Added NPX config for Claude Desktop

[minorun365]

Description

This PR adds environment variable configuration (GDRIVE_CREDENTIALS_PATH) to the NPX setup for the Google Drive server, allowing users to properly specify the path to their credentials file.

Server Details

• Server: gdrive
• Changes to: configuration examples (added GDRIVE_CREDENTIALS_PATH to NPX setup)

Motivation and Context

This PR addresses the issue where the credentials path wasn't explicitly specified in the NPX configuration. By providing clear examples in the README for how to set up after authentication, this reduces setup errors and improves user experience.

How Has This Been Tested?

The configuration changes have been tested with Claude Desktop and Amazon Q Developer CLI when running the Google Drive server via NPX. It correctly reads credentials from the specified path after the authentication process is completed.

Breaking Changes

Existing users don't need to update their configurations for this change, but explicitly specifying the credentials file path will make their setup more reliable.
