Can't install because of `Sake` dep instead of `sake`

Apparently, in META6.json of Sake sake is used as a name. Then:

Failed to resolve some missing dependencies

Start with the repository's META6.json dependency declaration and compare the Sake entry with the package name described in the issue. Run zef install --deps-only . to reproduce the failed resolution; done means dependency installation no longer reports Sake as missing.
