fix: 🐛 multiple lines on Windows (#210)

* fix: 🐛 multiple lines on Windows

The description input was disappearing on Windows because of the new
line character. This writes the commit message to a file first and then
uses the --file parameter to read from it.

✅ Closes: #188 #197

* refactor: 💡 improved code readability and execution flow

"command" was being built and escaped in multiple places, now its all in
one place

* test: 💍 update snapchot

* fix: 🐛 eslint

* fix: 🐛 command execution

* refactor: ♻️ change commit file to COMMIT_EDITMSG

* refactor: ♻️ move hook check down
