docs: fix self-hosting overview page GCP link and card descriptions

[devin-ai-integration]

Context

This PR fixes issues in the self-hosting overview page identified during review of PR #5106:

1. Bug fix: The GCP card was incorrectly linking to docker-swarm instead of gcp-native
2. Content fix: The Kubernetes card description was duplicated from the Docker card - now has a unique description
3. Formatting: Made all card descriptions consistent (all ending with periods)
4. Descriptions: Updated AWS and GCP card descriptions to be more specific about the deployment method (ECS with Fargate, GKE)

Also includes the expanded intro content and new deployment option cards (Docker Swarm, AWS, GCP) from the parent PR.

Steps to verify the change

1. Navigate to the self-hosting overview page in the docs
2. Verify the GCP card links to /self-hosting/deployment-options/gcp-native
3. Verify all card descriptions are accurate and end with periods
4. Verify the Kubernetes card description mentions "Helm chart" (not the Docker image text)

Greptile Overview

Greptile Summary

This PR fixes documentation issues in the self-hosting overview page, specifically correcting the GCP card link from docker-swarm to gcp-native and updating the Kubernetes card with a unique description mentioning the Helm chart. The changes also expand the intro content with compliance and flexibility details, and add new deployment option cards for Docker Swarm, AWS, and GCP.

• Fixed GCP card link to point to correct gcp-native path
• Updated Kubernetes description to mention Helm chart deployment
• Added expanded intro explaining compliance and flexibility benefits
• Added new deployment cards for Docker Swarm, AWS (ECS with Fargate), and GCP (GKE)
• The AWS and GCP documentation files (aws-native and gcp-native) could not be verified to exist in the repository

Confidence Score: 4/5

• This documentation-only PR is safe to merge with minimal risk.
• The changes are limited to documentation content (MDX file) with no code logic changes. The fixes correctly address the issues described in the PR (GCP link, Kubernetes description). One concern is that the AWS and GCP documentation files referenced may not exist yet, which should be verified before merging.
• Verify that target documentation files for AWS and GCP deployment options exist before merging.
