Replace node-sass with a portable sass to support old compilers

When I build JIFA on centos7, I got the following error.

8195 error gyp info spawn args [ 'V=1', 'BUILDTYPE=Release', '-C', 'build' ]

I guess, node-sass doesn't support the old compilers.
ref. sass/node-sass#483

And now node-sass is deprecated. It has been replaced by the more portable dart-sass.

If my understanding is correct, the following patch may resolve the issue.
