Ordinal explorer: "Coinbase height" is poorly understood add explainer

[314159265359879]

Is your feature request related to a problem? Please describe.
Many users do not know that "coinbase" means "block reward". They may wonder what coinbase.com (the centralized exchange) has to do with the inscription 😄.

Describe the solution you'd like
In this case I think "Coinbase block height" would be more descriptive . Additionally it could be helpful to have a little "i" or "?" to explain that it is the the block reward that created the inscribed sat.

Describe alternatives you've considered
You could just show "block" but then there could be confusion about "what block". The block the sat was inscribed or the sats birthblock? In this case it is about its birth.

Additional context

This is how it is displayed on an other explorer.
