Manuel de la Peña b951e92f57 feat(guides): migrate all testcontainers.com guides (#24505)
## Description

Migrate 17 Testcontainers guides from testcontainers.com into the Docker
docs site, covering Java (14 guides), .NET (2 guides), and Node.js (1
guide). This follows up on PR #24450 which added the initial Go and
Python guides.

Each guide is converted from AsciiDoc to Hugo Markdown, split into
multi-chapter stepper navigation, updated to the latest Testcontainers
API, and verified with passing tests running in containers.

Java guides use testcontainers-java 2.0.4 with the new 2.x Maven
coordinates and package names (e.g., `testcontainers-postgresql`,
`org.testcontainers.postgresql.PostgreSQLContainer`). The Quarkus guide
uses Quarkus 3.22.3 with TC 1.x managed by the Quarkus BOM, since no
released Quarkus version ships TC 2.x yet.

## How to test

All code snippets have been verified by running each guide's source
repository tests inside Docker containers with the Docker socket
mounted.

To re-run the verification, use the `/testcontainers-guides-migrator`
skill included in this PR
(`.claude/skills/testcontainers-guides-migrator/SKILL.md`). The skill's
Step 6 documents the exact container commands and macOS Docker Desktop
workarounds (host override, docker-java API version, etc.) needed to run
each language's tests:

```
/testcontainers-guides-migrator I want you to verify all the guides in this branch.
Do a full review, verifying that all code snippets compile, the code is executable,
and ALL the tests pass. Run them as docker containers, never locally.
```
