Remove cancelability from the dictionary

[enjoy-binbin]

cancelability and cancellability both are correct spellings.

Remove it from the dictionary
And add it to dictionary_rare.

We can see many uses here: https://linux.die.net/man/3/pthread_setcanceltype

@enjoy-binbin just because it's used in a real, large (and old) project doesn't mean necessarily that it's not a misspelling. For example, the V8 JavaScript engine (which powers Google Chrome and Node.js) has several C++ types defined which have Convertable in their names, which is a misspelling. The correct spelling is Convertible. https://github.com/v8/v8/search?q=convertable

I think you're right actually @enjoy-binbin: https://en.wiktionary.org/wiki/cancellability (lists https://en.wiktionary.org/wiki/cancelability as an alternate spelling).

It would be nice to see it in a commercial dictionary which probably spends more time and effort vetting it's entries.

I wonder if it should be rare rather than dropped entirely?

@enjoy-binbin will you please remove it from dictionary.txt and add it instead to https://github.com/codespell-project/codespell/blob/master/codespell_lib/data/dictionary_rare.txt?

[enjoy-binbin]

@bl-ue Sure. Already updated. Please check again for me.
ps sorry for the delay
