In order to avoid problems posed by potentially including the unconverted dependencies in the root autoloader, this package will hold all dependencies that require conflict avoidance.
This way it won't throw errors when building in 7.0 or 7.1
(required for CI). Still, an error will be thrown when manually
running move-vendor-packages.sh in 7.0 or 7.1.
A custom fork of the coenjacobs/mozart package is now used to change
the namespace of the appropriate packages (only league/container
for now) instead of the previously used prefix-vendor-namespaces script.
The packages are now moved to the src/Internal/Vendor namespace instead
of being modified in-place in the vendor directory. The namespaces
are thus now prefixed with Automattic\WooCommerce\Internal\Vendor
(previously it was just Automattic\WooCommerce\Vendor).
