fix(zk_toolbox): various ways of writing zksync (#2752)

## What ❔

- Fix casing of "ZKsync" in READMEs and console messages in
`zksync-era/zk_toolbox`
  - ZKsync - correct
  - zkSync - incorrect
  - ZkSync (pascal case)
- PS: Some of those pascal cases may have been in purpose - let me know
if I should revert any of those.


## Why ❔

- Matches newer branding
