The repositories https://github.com/brandonwamboldt/sublime-nginx and https://github.com/brandonwamboldt/sublime-hosts no longer exist, so CI fails to checkout the submodules when testing with all syntaxes and themes and validating licenses of our dependencies. We will need to:

• find a suitable fork if it is being actively maintained
• or vendor it ourself from a local checked out version
• or recreate a sublime-syntax from scratch and accept that highlighting will be different
• or drop the submodule and corresponding syntax highlighting
