IMO, the commit hash for Nim is not needed if we stick to the released stable versions of the compiler. (e.g. 1.2.16 or 1.6.8)

I do not like idea to put nimVersion in Starting beacon node log line. Also i do not like idea to keep only nimVersion because even right now specific nim version commit hash do not equal to nim version commit hash which is distributed and maintained by nimbus-build-system.

We might still need Nim specific commits in the future, especially as people try early for compat with 1.7/1.8 or before Nim 2.0
