This reverts commit bd97c3eb3b.
It turns out that this is actually an issue with the native font
stack in Bootstrap v5. Roboto is still in the font stack, but they
added `system-ui` to the beginning of the list and there is some
issue or inconsistency with the system-ui behavior on Linux.

Barely working port of the "snarky" (their words) new Bootstrap Blog
example that was introduced with Bootstrap v4.0.0, but as it exists
in Bootstrap v5 alpha 3 currently. This example replaced the classic
blog example that had been a part of Bootstrap for several years and
was replaced after v4 alpha.
The Hugo theme logic here comes from my existing "Hugo Bootstrap v4
Blog" theme.
