gs-details-page: use tabular figures for install progress
makes text less wobbly as percentage changes
I couldn't get latest main
to build on my system, so I tested this on 42.2
and cherry-picked it onto main
.
See https://blog.horizon-eda.org/misc/2020/02/19/ui.html for more detail on why this matters.
We're still missing the padding for <10%, but this change gets us mostly there.
