Prysm agent details in default graffiti

[kasey]

🚀 Feature Request

Description

By default many other clients include the client name + version/build info in the graffiti area of a proposed block, while still allowing the user to override this value with a flag.

Knowing the version of the client software that produced a block can be helpful for debugging. This also sets us up to align with a proposed engine api change enabling clients to easily include CL+EL identifiers in blocks, which will aid in analyzing the health of EL client diversity.

Describe the solution you'd like

Set the default graffiti to include the "prysm" agent identifier along with version/build information. We already have the option to customize graffiti, so we only need to change the default to include prysm build info.

Is there any chance of getting this feature included before Pectra? Everyone will need to update their clients, so it would lead to widespread adoption.

if no one's working on this issue yet, I'd love to take it on!

@one-three-three-seven This is technically a breaking change for users, so the only way we can have it in is in our v6 update(Pectra). Some users might be relying on the fact that Prysm's graffiti is empty
