Alias _.tail to _.last

[danielbayley]

Having just added an optional parameter to _.last—to enable plucking the last n elements from an array in #5842, I also propose that _.tail be aliased to _.last, so that we have better consistency between _.head/_.first, and _.tail/_.last methods. The existing functionality of _.tail—to return all but the first array element—could instead now be done like this:

const array = [1, 2, 3 ,4]
_.tail(array, -1) // [2, 3, 4]

This might be a breaking change, so maybe one for v5… But could also exist as something like this wrapper function in the meantime…

import last from './last.js';

function tail(array, n = -1) {
    const results = last(array, n) || []
    return [results].flat()
}

export default tail;

See also #5841, which adds similar functionality to _.head/_.first.

Thank you @danielbayley! Per #5842 we are removing first/last in favor of built-in Array#at.

@jdalton Same response as #5842 (comment):

That’s nice, but it doesn’t give you a range as is the point of this PR…
