[alexmanie]

Purpose

This pull request updates the development environment and corrects a project reference in the solution file.
These changes help ensure compatibility with newer tools and prevent build issues due to incorrect file paths.

Development environment update:

• Updated the base image in .devcontainer/Dockerfile from the .NET 8.0 Bookworm image to the .NET 10.0 Noble image, ensuring the dev container uses the latest .NET platform and Ubuntu base.

Solution/project configuration:

• Fixed the project file reference for WeatherApp in FunctionsMcpTool.sln to point to McpWeatherApp.csproj instead of the incorrect WeatherApp.csproj, resolving potential build or project loading errors.
