Database size and history expiry update

[MarekM25]

Update this page: https://docs.nethermind.io/fundamentals/database#database-size
to include information about history expiry.
For example, show the node size with history expiry enabled as the default, and also provide the size of a full node without history expiry.
We can also include a reference to the History Expiry page for more details.

Docs issues should be in their repo

@kamilchodola What about these database sizes? There were updates previously, but then they stopped.
