78610b01f6 docs: recommend DinD for container jobs (#1258)
Make Docker-in-Docker the recommended and first-shown setup. Mounting the host's Docker socket gives every job root-equivalent access to the host, while DinD gives jobs their own daemon. The default `latest` tag is unchanged.

Also shorten the image flavour docs to what users need to pick an image, and correct that `dind-rootless` needs `--privileged` too.

Closes https://gitea.com/gitea/runner/issues/1227

### Running `gitea-runner` using `docker-compose`
This uses the recommended Docker-in-Docker image, see [image flavours](../../README.md#image-flavours).
```yml
...
gitea:
image: gitea/gitea
...
healthcheck:
# checks availability of Gitea's front-end with curl
test: ["CMD", "curl", "-f", "<instance_url>"]
interval: 10s
retries: 3
start_period: 30s
timeout: 10s
environment:
# GITEA_RUNNER_REGISTRATION_TOKEN can be used to set a global runner registration token.
# The Gitea version must be v1.23 or higher.
# It's also possible to use GITEA_RUNNER_REGISTRATION_TOKEN_FILE to pass the location.
# - GITEA_RUNNER_REGISTRATION_TOKEN=<user-defined registration token>
runner:
image: gitea/runner:latest-dind
restart: always
privileged: true
depends_on:
gitea:
# required so runner can attach to gitea, see "healthcheck"
condition: service_healthy
restart: true
volumes:
- ./data/runner:/data
environment:
- GITEA_INSTANCE_URL=<instance url>
# When using Docker Secrets, it's also possible to use
# GITEA_RUNNER_REGISTRATION_TOKEN_FILE to pass the location.
# The env var takes precedence.
# Needed only for the first start.
- GITEA_RUNNER_REGISTRATION_TOKEN=<registration token>
```
### Running `gitea-runner` using rootless Docker-in-Docker
On AppArmor hosts such as Ubuntu and Debian, `security_opt` is needed for the daemon to start. Docker's `docker-ce-rootless-extras` package provides the `rootlesskit` profile.
```yml
...
runner:
image: gitea/runner:latest-dind-rootless
restart: always
privileged: true
security_opt:
- apparmor=rootlesskit
depends_on:
gitea:
condition: service_healthy
restart: true
volumes:
- ./data/runner:/data
environment:
- GITEA_INSTANCE_URL=<instance url>
- DOCKER_HOST=unix:///var/run/user/1000/docker.sock
# Use slirp4netns instead of vpnkit for significantly better network throughput.
- DOCKERD_ROOTLESS_ROOTLESSKIT_NET=slirp4netns
- DOCKERD_ROOTLESS_ROOTLESSKIT_MTU=65520
# When using Docker Secrets, it's also possible to use
# GITEA_RUNNER_REGISTRATION_TOKEN_FILE to pass the location.
# The env var takes precedence.
# Needed only for the first start.
- GITEA_RUNNER_REGISTRATION_TOKEN=<registration token>
```
