Update docker compose using Jaeger v2

[joe4dev]

Motivation

The previously used jaegertracing/all-in-one:latest image (Jaeger v1) is deprecated and now fails to start, so make otel is broken.

Changes

Upgrades docker-compose.tracing.yaml to Jaeger v2 (jaegertracing/jaeger:latest).

• Switches to the Jaeger v2 image with Badger embedded storage (7-day span TTL)
• Adds a named Docker volume (jaeger-data) so traces persist across container restarts
• Adds restart: unless-stopped and an explicit container_name

I'd love some feedback on https://github.com/localstack/localstack-pro/pull/6934, introducing OTEL=1 in LocalStack together with this fix 🙏 . You can check out feature/otel-flag and test Docker mode together with lstk.

FYI: I provide three tracing tool alternatives in this PR https://github.com/localstack/appinspector-workspace/pull/5

Thanks @joe4dev for the fix and improvement 👏
I just added one minor comment.

I am thinking we should also handle LOCALSTACK_OTEL and treat it as an alias to LSTK_OTEL since it is the name of the env var the emulator is using, so it can ultimately work across all LS products when set in the shell (not in the scope of your PR)

Will test together with your PR soon.
