Improve ergonomics of Title and LegendGroupTitle structs

[fsktom]

A small quality of life improvement

So that instead of doing

let layout = Layout::new().title(format!("<b>{title}</b>").as_str().into());

I can now do

let layout = Layout::new().title(format!("<b>{title}</b>").into());

[fsktom]

This is even better! Thanks @mfreeborn :)

 let layout = Layout::new().title(format!("<b>{title}</b>"));

is even cleaner now :D

[fsktom]

I'm going to go ahead and try to fix the failing examples etc. if that's alright with you

[mfreeborn]

Yes, start going for it by all means! I ran out of time updating the remaining examples etc last night. I also intend to give `LegendGroupTitle` the same treatment, which we might as well do in this PR.

@mfreeborn I tried improving LegendGroupTitle similarly to Title in 3feaa0c
Seemed to work fine, but I'm not sure if I did everything correctly

What do you think?

Seems like I missed some things... Now the clippy tests shouldn't fail
