Added support for DEVELOPMENT_TEAM environment variable (#562)

Add `export TUIST_DEVELOPMENT_TEAM=ABCDEFG123` (where `ABCDEFG123` is
your Apple development team ID) in your `.zshrc` or `.bashrc` file to
set the `DEVELOPMENT_TEAM` environment variable. Alternatively, run
`TUIST_DEVELOPMENT_TEAM=ABCDEFG123 tuist generate --path SampleApp` when
generating the project.
