Fix copy/paste of empty lines (#19798)
* Fix copy/paste of empty newlines again

Fixes: https://github.com/go-gitea/gitea/issues/19331
Regressed by: https://github.com/go-gitea/gitea/pull/18270

Needed to do another newline addition to the Chroma output HTML to get
copy/paste work again. The previous replacement conditions are probably
obsolete, but as I'm not 100% sure, I opted to keep them.

Specifically, the Chroma HTML change mentioned in
https://github.com/go-gitea/gitea/pull/18270#issuecomment-1013350246
broke our previous newline replacement for such empty lines.

Also included are a few changes to make the test more pleasant to work
with.

* run go mod tidy

* add util.Dedent

* copy in the code
