Remove deprecated @else-if statement, replace with @else if

[gunjam]

When compiling with the sass npm module I'm getting the following deprecation warning:

DEPRECATION WARNING on line 145, column 7 of node_modules/govuk-frontend/helpers/_typography.scss:
@elseif is deprecated and will not be supported in future Sass versions.
Use "@else if" instead.
    ╷
145 │     } @elseif $breakpoint == "print" {
    │       ^^^^^^^
    ╵

This should fix the issue, while still sucessfully building with the node-sass package.

Thanks for this, @gunjam!

Would you mind adding an entry to the changelog?

This will then need another review from someone else on the team before we can get it merged. It's also worth mentioning that we're currently working towards a 3.0 release and so it may take a while before this actually goes out.

Hi @36degrees, I updated CHANGELOG.md, did I do it right? :)
