feat(showcase): showcase sparkline widget

[mccartney]

Relates to #249.

Adding a showcase entry for Sparkline widget

[joshka]

There's a couple of small issues with this:

• We use git-lfs to avoid bloating the repo with images, but I think you might have just uploaded the image directly (I'm not super familiar with how to fix this up - possibly @orhun / @kdheepak / @Valentin271 can help?)
• The sparkline file needs to be formatted with rustfmt to fix up the line lengths

[joshka]

I'm not sure why, but I was also unable to directly update this branch to fix these issues when I tried.

That's probably because the PR is from my fork and you don't have permissions there.

I believe when you make a PR you can choose to allow maintainer to make edits:

If you have that checked, I believe we will be able to make changes to this PR even if it from a fork. No need to make a separate PR just for checking that option, but might be good to know for next time :)

And I think you have to run the following after installing git lfs:

git lfs install
git lfs pull

and then use git like normal to make commits. I've updated the website contributing section to explicitly state that: https://ratatui.rs/developer-guide/website/

It seems like you've figured this out though, because the test that @Valentin271 set up is passing! So this PR looks good to me.

Thanks for fixing this up. I've merged the change.

[mccartney]

Indeed
https://api.github.com/repos/ratatui-org/website/pulls/471
shows

maintainer_can_modify: false

And TIL it's changeable after the PR is created. At the bottom of the right-hand-side panel:

I could have sworn that I checked that that was ticked on the UI earlier, which was what confused me about this. Heisenbugs...

And I was convinced I've checked that when creating the PR :)

Anyway. Have a nice week.
