Fix `setup.sh` and sort files on search

[elanzini]

1. With the current setup.sh, files are unpacked in resources/resources and lsp/lsp. This means that locally the search doesn't work because it looks for rg in resources/darwin/.., not in the resources/resources folder.

2. Added the --sort-files flag to sort the files in the result of the search
