Prevent overwriting existing libraries and platforms at first IDE start-up (#1169)

* move initialization of libs and platforms into new contribution

* use noOverwrite when install built-in libraries and platform

* catch errors when installing platforms and libraries at first start-up

* arduino-cli version 0.25.0-rc1

* refine platforms and libraries initialization in case of errors

* add trailing newline when libraries and platform installation fail

* use regex to check error if builtin library dependencies are already installed

* rename contribution
