fix: avoid shadowing of 'err' in version parsing for plugin and config packages

Renamed inner error variables in version parsing logic in pkg/plugin/version.go and
pkg/config/version.go from 'err' to 'errParse' to avoid shadowing the outer 'err' variable.
This improves clarity in control flow and prevents potential confusion in error handling.
