docs(docs): update Docker to ClickHouse 25.7 with vector_similarity support (#32659)

Browse Source 
- **Description:** Updated Docker command to use ClickHouse 25.7 (has
`vector_similarity` index support). Added `CLICKHOUSE_SKIP_USER_SETUP=1`
env param to [bypass default user
setup](https://clickhouse.com/docs/install/docker#managing-default-user)
and allow external network access. There was also a bug where if you try
to access results using `similarity_search_with_relevance_scores`, they
need to unpacked first.

- **Issue:** Fixes #32094 if someone following tutorial with default
Clickhouse configurations.
