As mentioned in goquery's documentation (https://pkg.go.dev/github.com/PuerkitoBio/goquery#Single):

the Matcher returned by Single, at most the first match will be selected.

be considered as buggy and fixed.
This shaves off 2MB from the miniflux binary, which is quite steep for a
feature that nobody is/should be using, and remove a dependency which is always
a good thing.
- Online some one-line functions
- Transform a free-standing function into a method
- Massively simplify `removeClickbait`
- Use a proper constant instead of a magic number in `applyFuncOnTextContent`
