Update to v25.10

Warning

Make a backup before performing the following steps.

Ensure that Docker Compose version 2 is installed:
```
docker-compose version --short
```
Upgrade if required. MITIGATOR no longer supports Docker Compose version 1.
Remove elements unsupported by Docker Compose v2 from .env file:
```
sed -e 's/\b\(docker-compose.yml\):\1/\1/' -i .env
```
Stop MITIGATOR:
```
docker-compose down
```

Remove version: "2.2" from all Docker Compose YAML files:

for file in $(sed -n 's/^COMPOSE_FILE=\(.*\)$/\1/p' .env | tr : ' '); do sed -i '/^version: "2.2"$/d' $file; done
