docs: enclosing in backticks

[LeoniePhiline]

Reading https://docs.rs/eyre/latest/eyre/struct.Report.html#display-representations I found that some items should better be enclosed in backticks.

I'll happily fix that, I merely want to ask in advance:

When enclosing parts of strings in backticks, do you then prefer backticks + quotes, or only backticks?

I personally prefer backticks + quotes, to signify "this is code, but it's a string literal".

Here an example (look out for the curly braces):

1. backticks + quotes: When you print an error object using "{}" or to_string(), only the outermost underlying error is printed, not any of the lower level causes. This is exactly as if you had called the Display impl of the error from which you constructed your eyre::Report. [...] To print causes as well using eyre’s default formatting of causes, use the alternate selector "{:#}".
2. only backticks: When you print an error object using {} or to_string(), only the outermost underlying error is printed, not any of the lower level causes. This is exactly as if you had called the Display impl of the error from which you constructed your eyre::Report. [...] To print causes as well using eyre’s default formatting of causes, use the alternate selector {:#}.

Backticks + quotes is okay. Thanks 😄
