Use weighted algorithm for string matching when finding files in repo (#21370)
This PR is for:
* https://github.com/go-gitea/gitea/issues/20231

Now, when a user searches `word`, they always see `/{word}.txt` before
`/{w}e-g{o}t-{r}esult.{d}at`

Demo:

When searching "a", "a.ext" comes first. 

Then when searching "at", the longer matched "template" comes first.

This PR also makes the frontend tests could import feature JS files by
introducing `jestSetup.js`
