Bash test nested incorrectly; leads to syntax error

[bicobus]

Offending line: https://github.com/KittyKatt/screenFetch/blob/e2ca5ae907c7466c23b7286d11cb4a8b7763f1d1/screenfetch-dev#L3025

[ is an alias for test, as such it doesn't support logical OR operations. The line should be rewritten to use [[ instead.
