Double quote variable to prevent sh error
During build of the image, this error message appears:

    Step 12/27 : RUN if [ ${release} == 1 ] ; then         crystal build ./src/invidious.cr         --release         --static --warnings all         --link-flags "-lxml2 -llzma";     else         crystal build ./src/invidious.cr         --static --warnings all         --link-flags "-lxml2 -llzma";     fi
     ---> Running in 44d8a5cd1f96
    sh: 1: unknown operand

When double-quoting the variable according to [shellcheck's SC2086](https://github.com/koalaman/shellcheck/wiki/SC2086), the error notice is gone.
