chore: normalize separator in content on the viewport meta tag

[davidmurdoch]

The functionality is the same as before, but it this change works around a bug in https://github.com/terser/html-minifier-terser which causes the space to be removed, and the tag to become invalid (this only affects the webpack build).

Upstream issues:

webdiscus/html-bundler-webpack-plugin#106
terser/html-minifier-terser#178

I confirm the problem on the webpack branch when I run
yarn webpack --env production --no-lavamoat
but the problem does not appear on just yarn webpack, I guess it doesn't get minified
