Changes included in v0.12.0:

Changelog

🚀 Features

[DEVELOPER]

• Bump Gardener dependency to v1.137 and use Gardener api module instead of hacky script to depend on the Gardener api types. (#187, @Diaphteiros)

[OPERATOR]

• The new enforcedShootExtensions field in the providerconfig's spec allows to specify shoot extensions which should always be set. For backward compatibility reasons, the shoot OIDC extension will be enforced by default if the field is not set (or set to null). Setting the field to an actual list - either empty or with entries - disables the shoot OIDC extension, unless it is part of the list. (#188, @Diaphteiros)
