Ensure test functions use t as their parameter

The convention is to have the parameter in tap's test function be named t. Most rules in eslint-plugin-tap are based on that assumption.

Fail

import tap from 'tap';

tap.test('test name', boop => { // Incorrect name
	t.pass();
	t.end();
});

tap.test('test name', (t, bar) => { // too many arguments
	t.pass();
	t.end();
});

tap.test('test name', (bar, t) => { // too many arguments
	t.pass();
	t.end();
});

Pass

import tap from 'tap';

tap.test('test name', () => {
	// ...
});

tap.test('test name', t => {
	t.pass();
	t.end();
});
