fix redis/redisinsight image tag

### 🔖 Enhancement description The redis-insight service in docker-compose.yml (branch 1.9.x) is currently using the latest tag (https://github.com/appwrite/appwrite/blob/1.9.x/docker-compose.yml). This can cause inconsistent environments and unexpected breaking changes. I'd like to update it to a specific stable version (e.g., 3.2) to ensure environment stability and reproducibility, following the project's standards. ### 🎤 Pitch Using the :latest tag is a mutable reference, which means the image can change at any time without a change in the docker-compose.yml file. This leads to: Inconsistent environments: Different developers might pull different versions of the image. Unexpected breaking changes: An automated update to the latest tag could introduce bugs or configuration mismatches. Lack of version control: It's impossible to roll back to a known working state if the latest image is updated with issues. The image tag will be updated to a specific, stable version (e.g., redis/redisinsight:3.2). **Example Change:** image: redis/redisinsight:latest image: redis/redisinsight:2.54.0 This ensures that every time someone runs docker-compose up, they are using the exact same version of RedisInsight. ### 👀 Have you spent some time to check if this issue has been raised before? - [x] I checked and didn't find similar issue ### 🏢 Have you read the Code of Conduct? - [x] I have read the [Code of Conduct](https://github.com/appwrite/.github/blob/main/CODE_OF_CONDUCT.md)
