Add Revision UI while generating a content entity

[bhanu951]

As per the Issue #2350939 on Drupal.org we can have Revision UI for Revisionable Entities.

Update Content Entity Generator class to include Revision UI annotations in Entity Class .

The CR has additional details for the syntaxes

Edit:

We might need to consider the changes that might be introduced in the issue #2976861 as well. Thanks.

Related #39.

The revision UI for custom entities will be available in Drupal ~~8.1~~ 10.1. I wonder if we can support it without breaking compatibility with Drupal ~~8.0~~ 10.0.

I'm surprised this module is supporting Drupal 8.0? Drupal 8 (especially 8.0) is pretty far past end of life.

Sorry, I misspelled versions in the previous comment. DCG 3 supports only Drupal 10.

[greggles]

OK, got it. Looks like Drupal 10.0 will be with us until December 13, 2023 (UTC) so I agree it's good to support that :)

Thanks!

Fixed in #128.
