fix: Precommit config overwritten on init

[itoltz]

secureli-570

An existing precommit config file will be overwritten when running secureli init.

I've added a flag to the init action to prevent overwriting the config-- `secureli init --preserve-precommit-config'

Changes

• Added --preserve-precommit-config parameter to init action

Testing

• Added copy of existing test with the flag added
