Update the cachetools dependency upper bound from <7 to <8 to support cachetools 7.0.0. Streamlit only uses TTLCache directly, which is not affected by breaking changes to @cached and @cachedmethod decorators in cachetools 7.

Pull request overview
This PR updates the cachetools dependency constraint from <7 to <8 to support cachetools 7.x versions. The breaking changes in cachetools 7.0.0 only affected the @cached and @cachedmethod decorators, which Streamlit does not use. Streamlit exclusively uses the TTLCache class, which remains backward compatible.
