feat: allow for configuring the indent character in JSON files

[ieedan]

shadcn and some others like to format their files in insane (different) ways. The normal ones prefer tabs but the rest of the barbarians are formatting with 2 space. While I don't accept their lifestyle I can accommodate it by allowing others to configure it.

This will prevent you from getting huge diffs just because of formatting differences when migrating to jsrepo
