Make Bundle attribute repeatable

I believe this is a core limitation, you'll get an AmbiguousBundleClassException

For me it works fine without errors with patch from that MR.

#[Bundle(
  entityType: 'taxonomy_term',
  bundle: 'coupons',
  label: new TranslatableMarkup('Region'),
)]
#[Bundle(
  entityType: 'taxonomy_term',
  bundle: 'leaflets',
  label: new TranslatableMarkup('Region'),
)]
class MyTerm extends Term {}

No worries are you able to update the test coverage?
