ISNBAT use the CoBlocks buttons block in Gutenberg 7.2.0

[mmtr]

Describe the bug
The Buttons block from CoBlocks does not work when using the incoming Gutenberg 7.2.0. It might be related to the addition of a similar Buttons block introduced in Gutenberg 7.2.0 (WordPress/gutenberg#17352).

To Reproduce

1. Download, install and activate Gutenberg 7.2.0 RC
2. Insert a Buttons block from CoBlocks.
3. Buttons are in different lines. Neither text nor URLs can be entered.

Gutenberg 7.2.0 RC	Gutenberg 7.1.0

Expected behavior

Not sure, but there are several options:

• Deprecate the CoBlocks Buttons block in favor of the new one from Core.
• Rename the CoBlocks Buttons block so there are no 2 blocks with the same name.
• If CoBlocks Buttons block remain active, it should behave like before (buttons are in the same line, and text or URLs can be entered).

Isolating the problem:

• This bug happens with no other plugins activated
• This bug happens with a default WordPress theme active
• This bug happens without the Gutenberg plugin active
• I can reproduce this bug consistently using the steps above

WordPress Version
5.3.2

Gutenberg Version
7.2.0 RC

Yea we definitely would like to deprecate our Buttons block for the version in 7.2.0, but there's not a clear way to deprecate blocks into other blocks just yet - but we're looking into it.

The ideal situation would be: if there's a core/buttons block registered, auto-transform the coblocks/buttons block into the core version.
