Suggestion to remove authorizations::create from doc

[rafasashi]

It seems that the following method doesn't exist any longer or am I missing a dependency?

php-github-api/doc/authorizations.md

Line 25 in 3467a34

$authorization = $github->api('authorizations')->create($data);

php-github-api/doc/two_factor_authentication.md

Line 18 in 9c57106

$authorization = $github->api('authorizations')->create(array('note' => 'Optional'), $code);

These endpoints were indeed deprecated and removed in V3. (2fe12b8)

Can you send a PR to cleanup the docs @rafasashi? Thanks!
