Config updates

[rdlrt]

Description

• Update config templates to mirror naming convention as on cardano-playground repo
• Clone book.play.dev.cardano.org version (with minor differences to avoid having to maintain a seperate submitapi config)
• Update corresponding doco
• Rename default logging (node0.json => node.json) and socket (node0.socket => node.socket) to be consistent with IO's naming.
• [Unintended for this PR - but might as well] setup-grest.sh - No longer need to trigger epoch-summary-corrections cron job for Koios, the functions still left as-is in case the bug (or a version of it) re-appears in future

Motivation and context

• book.world.cardano.org updated config links from their github, and old peers retired - and unless part of calls, this could have been missed. In order to not be dependent on upstream changes - and more importantly - add some version matching of current supported repo configs with the scripts , while maintaining history - the configs are being cloned to this repo, while adding addendum for logging to be JSON based + setting known tracers (eg: ones used by blockPerf) on guild-ops repo

How has this been tested?

Applied forced update on guild node and restart node/dbsync after re-applying topology/env/cnode.sh user variable customisations.

looks okay to me.
