Helix is no longer compatible with Sveltekit page and layout naming conventions

[DaveTJones]

Summary

Attempting to create a new page or layout file for Sveltekit by passing the desired name of the file to Helix as an argument now results in an error:

> hx +layout.svelte

Error: could not parse arguments

Caused by:
    bad line number after +

This can be worked around, but is annoying. Could this be avoided by providing fallback behaviour or parsing arguments which have a file extension differently to other arguments? If so I'm happy to try implementing a fix.

Reproduction Steps

I tried this:

1. hx +layout.svelte

I expected this to happen:
A buffer to open that would later be saved as '+layout.svelte'

Instead, this happened:
Helix attempted to parse the file name as a line number

I think it's reasonable to interpret the argument as a file if we can't parse the number instead of returning an error like we do now. In this block:

helix/helix-term/src/args.rs

Lines 92 to 97 in 17dd102

	arg if arg.starts_with('+') => {
	let arg = &arg[1..];
	line_number = match arg.parse::<usize>() {
	Ok(n) => n.saturating_sub(1),
	_ => anyhow::bail!("bad line number after +"),
	};

let's set line_number when the arg.parse::<usize>() is ok and push the arg to the args.files vec otherwise.
