Fix: Undefined array key warning / Require wp-cli 2.11

[BrianHenryIE]

PHP Warning:  Undefined array key "hook" in /.../wp-cli/handbook/bin/command.php on line 438

The $cmd['hook'] value

handbook/bin/command.php

Line 426 in bebc75b

$hook_name = $cmd['hook'];

which stems from

handbook/bin/command.php

Line 168 in bebc75b

'cli cmd-dump',

which uses CLI_Command::command_to_array()

was added in the (yet to be released) v2.11 (vs v2.10) – wp-cli/wp-cli@6d78633.

This PR adds "wp-cli/wp-cli": "^2.11" to composer.json so the correct minimum version is used.

Did you follow these steps?

wp cli update --nightly
bin/install_packages.sh
WP_CLI_PACKAGES_DIR=bin/packages WP_CLI_CONFIG_PATH=/dev/null wp handbook gen-all

Generally handbook commands docs are generated with nightly version.

Makes sense to have that explicitly reflected in the composer dependencies 👍
