- In the case that [go-enry](https://github.com/go-enry/go-enry/)
returned langauge doesn't match a lexer name (Either because its not
available or because it doesn't match Chroma's name), a last effort
attempt is made to use Chroma's matching.
- go-enry already applies `strings.ToLower` onto the filename to avoid
being case-sensitive, add the same code for Chroma's matching. The code
being used doesn't rely on the filename being case senstive for correct
matching.
- Adds unit test.
- Resolves #752
(cherry picked from commit dcc442351d)

* 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

Use check attribute code to check the assigned language of a file and send that in to
chroma as a hint for the language of the file.

* Ensure empty lines are copiable and final new line too
When files are highlighted the newline character needs to be added in a whitespace
compliant mode. Also ensure the final empty newline is rendered.
