Upgrade sass-loader to 10.0.5 (#18972)

`node-sass` v5 introduced support for Node.js v15, which is not supported by v4. However, Next.js currently errors with
```
Error: Node Sass version 5.0.0 is incompatible with ^4.0.0.
```
when attempting to build with `node-sass` 5.0.0. This error comes from `sass-loader`. They have recently released version 10.0.5 which supports `node-sass` 5.0.0 (PR <webpack-contrib/sass-loader#899>, release <https://github.com/webpack-contrib/sass-loader/releases/tag/v10.0.5>).
