Pin Docker image versions in compose.yaml files instead of using 'latest'

[coderabbitai]

Description

Docker appears to download images repeatedly even when no new releases have been conducted, when using the latest tag. Consider pinning to dedicated stable versions instead across all compose.yaml files.

Context

This concern was raised during review of PR #367, which introduces Docker/Podman Compose configurations across multiple integration guides.

Affected Files

Multiple compose.yaml files across the repository, including:

• docs/integrate/influxdb/compose.yaml
• docs/integrate/amqp/compose.yaml
• docs/integrate/collectd/compose.yaml
• docs/integrate/mongodb/compose.yaml
• docs/integrate/mqtt/compose.yaml
• docs/integrate/mysql/compose.yaml
• docs/integrate/oracle/compose.yaml
• docs/integrate/postgresql/compose.yaml
• docs/integrate/statsd/compose.yaml
• docs/integrate/telegraf/compose.yaml
• And others

Recommendation

Replace latest tags with specific version tags (e.g., crate:5.9.5, influxdb:2.7) to ensure reproducible builds and avoid unnecessary downloads.
