Merge Availability and AutofixKind

[JonathanPlasse]

Implement suggestion from @MichaReiser

NIt: Unrelated to this change: A Availability::None would remove the need for Option<AutofixKind>. It would then simply be AUTOFX: AutofixKind = AutofixKind::NONE (we could even inline Availability into AutofixKind

Nice. Thanks for working on this improvement :)

[MichaReiser]

Nit: We could implement Display for AutofixKind. You could then write this as

Suggested change

	match rule.autofixable() {
	AutofixKind::Sometimes => {
	output.push_str("Autofix is sometimes available.");
	output.push('\n');
	output.push('\n');
	}
	AutofixKind::Always => {
	output.push_str("Autofix is always available.");
	output.push('\n');
	output.push('\n');
	}
	AutofixKind::None => {}
	}
	let autofix = rule.autofixable();
	if matches!(autofix, AutofxKind::Sometimes | AutofixKind::Always) {
	writeln!(output, "{autofix}\n").unwrap(); // Writting to a string never fails except if the program OOms
	}

and then re-use the same logic in generate_docs

[JonathanPlasse]

I do not know the term OOms. What does it mean?

[MichaReiser]

Oh, sorry. I should avoid using acronyms, and that's my java background shining through. OOM is an acronym for Out of Memory (exception in Java). And OOms is the activity when the program runs out of memory. The equivalent in Python is probably the MemoryError
