Add resource_templates to MCP::Client

[sjrct]

This adds support for querying resource templates to the MCP::Client

I also removed an unused require from logging_message_notification.rb

Motivation and Context

Prior there was no MCP::Client interface for listing resource templates

How Has This Been Tested?

I tested it with the following script with an mcp server I have:

require_relative 'lib/mcp'

transport = MCP::Client::HTTP.new(url: "http://localhost:8080/mcp")
client = MCP::Client.new(transport: transport)

templates = client.resource_templates

templates.each do |template|
  puts JSON.pretty_generate(template)
end

And added tests to test/mcp/client_test.rb

Looks good to me. Can you squash your commits into one?

Good catch. This removal is outside the scope of the changes intended in this PR, so it would be better to split it into a separate PR if possible.

Sure thing, done.
