Some files in truffle package needs to be excluded from using prettier in git commits

Issue

Truffle uses prettier for consistent code style across the whole codebase. But there may be some files that need to exclude the use of prettier in the git commits. For example, truffle-config.js in packages/core/lib/commands/init/initSource has few trailing commas that are needed, which are automatically removed by prettier once that file is committed. We generally use --no-verify flag while committing that file, which is not an ideal solution.

There should probably be a way to exclude certain files from using prettier in the commits.
