Minor Changes

#7532 9e5fafa2b Thanks @ematipico! - The astro/middleware module exports a new utility called trySerializeLocals.
This utility can be used by adapters to validate their locals before sending it
to the Astro middleware.
This function will throw a runtime error if the value passed is not serializable, so
consumers will need to handle that error.

#7532 9e5fafa2b Thanks @ematipico! - Astro exposes the middleware file path to the integrations in the hook astro:build:ssr

// myIntegration.js
import type { AstroIntegration } from 'astro';
function integration(): AstroIntegration {
  return {
    name: 'fancy-astro-integration',
    hooks: {
      'astro:build:ssr': ({ middlewareEntryPoint }) => {
        if (middlewareEntryPoint) {
          // do some operations
        }
      },
    },
  };
}

The middlewareEntryPoint is only defined if the user has created an Astro middleware.

#7432 6e9c29579 Thanks @ematipico! - Adds a new command astro info, useful for sharing debugging information about your current environment when you need help!

#7532 9e5fafa2b Thanks @ematipico! - The astro/middleware module exports a new API called createContext.
This a low-level API that adapters can use to create a context that can be consumed by middleware functions.
#7532 9e5fafa2b Thanks @ematipico! - Introduced a new build option for SSR, called build.excludeMiddleware.
```
// astro.config.mjs
import { defineConfig } from 'astro/config';

export default defineConfig({
  build: {
    excludeMiddleware: true,
  },
});
```
When enabled, the code that belongs to be middleware won't be imported
by the final pages/entry points. The user is responsible for importing it and
calling it manually.
