docs: CrateDB: Educate readers about full and semantic cache components (#29000)
Dear @ccurme and @efriis,
following up on our initial patch adding documentation about CrateDB
[^1], with version 0.1.0, just released, the [CrateDB
provider](https://python.langchain.com/docs/integrations/providers/cratedb/)
starts providing `CrateDBCache` and `CrateDBSemanticCache` classes. This
little patch updates the documentation accordingly.
Happy New Year!
With kind regards,
Andreas.
[^1]: Thanks for merging
https://github.com/langchain-ai/langchain/pull/28877 so quickly.
