We've switched to dashes
The shebang is thrown away so this has no end-user impact
According to the [RFC](https://rust-lang.github.io/rfcs/3503-frontmatter.html): > Opens with 3+ dashes followed by 0+ whitespace, > an optional term (one or more characters excluding whitespace and commas), > 0+ whitespace, and a newline
From the [RFC](https://rust-lang.github.io/rfcs/3503-frontmatter.html) > When parsing Rust source, after stripping the shebang (#!), rustc will strip the frontmatter: > > - May include 0+ blank lines (whitespace + newline) The question is what is a non-newline whitespace and what is a newline. Looking at the [Reference](https://doc.rust-lang.org/reference/whitespace.html), the answer is "unsure", particularly because the Rust language doesn't generally try to distinguish them. I kept things basic for now and we can revisit later.

What does this PR try to resolve?
We removed rejected syntax in #13861 haven't update frontmatter parsing to what RFC 3503 says.
This adds tests and fixes various cases to ensure we correctly detect the frontmatter and the infostring.
This is part of #12207
How should we test and review this PR?
