test(paragraph): simplify paragraph benchmarks

[joshka]

Reduce benchmarks from 60 calls to 18. Now 3 different line counts
(64, 2048, 65535) * 6 different tests (new, render, scroll half / full,
wrap, wrap and scroll)

@haydenflinner given you're recently been benchmarking, do these look a little better to you?

Yep, looks good to me! I was surprised at how many paragraph benches there were, prior. This looks more representative too.

Looks so much better, thanks a lot for this man !

Out of curiosity, do you know what made the code coverage regress a little bit src/widget/mod.rs ?

Looking at https://app.codecov.io/gh/tui-rs-revival/ratatui/pull/282/indirect-changes?src=pr&el=tree-more, it suggests that we probably don't have a test case for one branch of the Debug impl on Borders (which wasn't tested by this code 🤷‍♂️).
