config: declare and use the latest stable hardfork

Differentiate released and stable ones from test-only not-yet-ready and such.
Enabled only stable ones by default to avoid surprises in private networks
when some beta hardfork is made available with some node release.

Fixes #3719.

This change is implemented in the [reference](https://github.com/neo-project/neo/pull/3301), but NeoGo has never had this bug, thus proper behaviour is preserved even before HFDomovoi. It results in the fact that some T5 transactions have different ApplicationLogs comparing to the C# node, but the node states match.
