Disabling "remove dot segments" behavior

I have a use-case where I need to be able to construct URLs that end in …/. or …/..[^1]; however, the url crate insists on removing dot segments no matter what API I go through, even when the dots are percent-escaped, e.g.:

fn main() {
    let url = url::Url::parse("https://example.com/path/%2e%2e").unwrap();
    // Prints "https://example.com/":
    println!("{url}");
}

Is there currently a method to construct a URL like this using this crate? If not, could such a method be added?

[^1]: Specifically, this is for manipulating GitHub labels via the GitHub REST API; if a user names a label with dot or dot-dot, the URL ends up with dots at the end.

Start with the Url::parse entry point and compare its behavior with RFC 3986 section 5.2.4, linked in the issue. Determine whether the crate already exposes a way to preserve trailing dot segments and what API shape is needed if it does not. Done means a supported construction path can retain URLs ending in /. or /.., with the behavior covered by tests.
