chore: Bump nimbus and nim to latest available - nim-2.0.12

[NagyZoltanPeter]

Description

To unstuck waku-sync v2 we need to move to latest nim version.
Currently it is 2.0.12

Changes

• nimbus-build-system is bumped to latest master that includes nim v2.0.12

Note:

Currently, this new nim version breaks our code. We need to investigate if it is possible to adjust nim flags for backward compatible build or we can easily adjust our code.

Example error appears with latest nim version:

Issue

#3204

[NagyZoltanPeter]

Seems recent change in nim-restul/result.nim, that defines on the fly template named value collide in json readValue's procs where unrecognizedFieldWarning template expects also to a variable named value. It resulted ambiguous type resolution in our template with result.value proc.

Eliminating this value expectation in unrecognizedFieldWarning let our code compile with nim 2.0.12
