📚 Description

Previously we were using degit and then tiged for cloning repository. They were not quite stable and had issues with subdir handling and also because of depending on local git command, fail with strange issues. This PR migrates to use unjs/gitget that is designed for best performance and not depending on local git. It also adds --force, --offline, --prefer-offline flags and (experimental) --shell that replaces working dir.

Note: -v|--verbose previously passing to tiged is deprecated. Using DEBUG=1 environment variable to enable global verbose logs is possible.
