Improve warning around setting up network attachments

We want to strongly recommend using a connection
preference that is secure but keep the
instructions open for a user that may not be as
concerned with security or just wants to
prioritize deploying quickly just to try out the
service.

This lets you manually approve trusted connections, as this setting cannot be changed later. To start, you can leave the list of accepted projects empty and add the NGINXaaS deployment project after it is created.
-   - For **development use cases**, you can set the **Connection preference** to **Automatically accept connections from all projects**, which allows connections without manual approval. If you choose this option, you don't need to explicitly allow the NGINXaaS deployment project.

See [Google's documentation on creating a network attachment](https://cloud.google.com/vpc/docs/create-manage-network-attachments#create-network-attachments) for a step-by-step guide. To ensure secure and controlled access to your network attachments, we strongly recommend configuring the **Connection preference** on the Network Attachment resource to **Accept connections from selected projects**. This option helps maintain security by ensuring only trusted providers can connect to your service by letting you manually approve trusted connections. To start, you can leave the list of accepted projects empty and add the NGINXaaS deployment project after it is created.

+   For development and testing purposes, or in scenarios where speed and simplicity are prioritized over security, you have the option to configure the **Connection Preference** to **Automatically accept connections for all projects**. Please note that this approach is inherently less secure and may expose your service to unintended or unauthorized access. We encourage you to exercise caution if using the less restrictive option and to avoid using it in production or sensitive environments.

 1. Make a note of the network attachment ID as it will be needed in the next steps to create your NGINXaaS deployment. You can find the network attachment ID in the Google Cloud Console by following the steps below:
    1. Go to Network Attachments at the following link: https://console.cloud.google.com/net-services/psc/list/networkAttachments?project=my-google-project (replace `my-google-project` in the URL with your project name).
    1. Open the desired network attachment and copy the value from the `Network Attachment` field. **Example format:** `projects/my-google-project/regions/us-east1/networkAttachments/my-network-attachment`.
