…et (#12348)

* Increase FinalityDepth & HistoryDepth defaults to match Polygon mainnet

We have verified that finality tags on zkevm polygon are just as far
behind latest as they are on other polygon chains (often 300-500
blocks). HistoryDepth needs to be larger for the same reason, and allow
room for uncles.

* Add Cardona defaults based on Goerli

and increase FinalityDepth & BlockHistoryDepth for both chains

* make config-docs

* pnpm changeset

* Re-run "make config-docs"
