* WIP * Set public_suffix to a pre Ruby 2.6 version * we don't need to install python * Stretch->Buster * Bump versions in lib.star * Manually update linter Sort of messy, but the .mod-file need to contain all dependencies that use 1.16+ features, otherwise they're assumed to be compiled with -lang=go1.16 and cannot access generics et al. Bingo doesn't seem to understand that, but it's possible to manually update things to get Bingo happy. * undo reformatting * Various lint improvements * More from the linter * goimports -w ./pkg/ * Disable gocritic * Add/modify linter exceptions * lint + flatten nested list Go 1.19 doesn't support nested lists, and there wasn't an obvious workaround. https://go.dev/doc/comment#lists
