Composer broken by latest release of lando/php

[NickDickinsonWilde]

When rebuilding containers that used to work, composer is no longer available.

example config:

recipe: drupal11
config:
  composer: 2-latest
  via: nginx
  database: mariadb:10.11
  xdebug: false
  php: 8.4
  webroot: web

(also happening with drupal10 recipe for another developer).

This is both before and after running lando update and installing latest (1.7.0) lando/php - I'm assuming that is not fixing it due to nesting of dependencies.
