docs: templates updated titles (#25646)

Browse Source 
Updated titles into a consistent format. 
Fixed links to the diagrams.
Fixed typos.
Note: The Templates menu in the navbar is now sorted by the file names.
I'll try sorting the navbar menus by the page titles, not the page file
names.

# Neo4j Cypher memory
# neo4j-cypher-memory
This template allows you to have conversations with a Neo4j graph database in natural language, using an OpenAI LLM.
It transforms a natural language question into a Cypher query (used to fetch data from Neo4j databases), executes the query, and provides a natural language response based on the query results.
Additionally, it features a conversational memory module that stores the dialogue history in the Neo4j graph database.
This template allows you to have conversations with a `Neo4j` graph database in natural language, using an OpenAI LLM.
It transforms a natural language question into a `Cypher` query (used to fetch data from Neo4j databases), executes the query, and provides a natural language response based on the query results.
Additionally, it features a `conversational memory` module that stores the dialogue history in the Neo4j graph database.
The conversation memory is uniquely maintained for each user session, ensuring personalized interactions.
To facilitate this, please supply both the `user_id` and `session_id` when using the conversation chain.
