Cater for duplicate field names with different keys

[bobbingwide]

In s.b/oikcom I must have created the ACF field blocks for the fields in the Basic group before I created the Layout group.
However I note that the attributes don't show the expected value for the field key ( _acf_field_name ).

<!-- wp:acf-field/acf-field {"name":"acf-field/acf-field",
"data":{"acf-field-name":"text","_acf-field-name":"field_645f589a88304"},
"mode":"edit","backgroundColor":"very-light-gray","fontSize":"normal"} /-->

However I note that the attributes don't show the expected value for the field key ( _acf_field_name ).

What we see in the data attribute are two values for acf-field-name and _acf-field-name
The value for acf-field-name is the user friendly field name.
The value for _acf-field-name is the ACF internal name for the acf-field-name attribute.
It's NOT the ACF internal name for the text field.

I believe I need to change the code such that the field name is actually the field's key.

Having done this the HTML for the block is simplified
For the original text field it becomes

<!-- wp:acf-field/acf-field {"name":"acf-field/acf-field",
"data":{"field_645f589a88304":"field_64aa869f48df7"},
"mode":"preview"} /-->

For the cloned field in the Layout group it becomes.

<!-- wp:acf-field/acf-field {"name":"acf-field/acf-field",
"data":{"field_645f589a88304":"field_64abd97b8ff80_field_64aa869f48df7"},
"mode":"edit"} /-->

It would appear that the simplified version is only temporary; it's what's displayed in the Code Editor when in edit mode.

When saved the data attribute is more complicated.

<!-- wp:acf-field/acf-field {"name":"acf-field/acf-field",
"data":{"acf-field-name":"field_64aa869f48df7","_acf-field-name":"field_645f589a88304"},
"mode":"edit"} /-->

The value for the acf-field-name attribute in data is now the field's key. This is currently used to generate the classNames for the div.

<div class="acf-field-field_64aa869f48df7 acf-type-text has-text-align- wp-block-acf-field-acf-field">rendered text field</div>

It would be nice to be able to map the key back to the name given by the user.
This would improve the message shown when the field is not set.

<p>Field field_64aa869f48df7 not set for post ID 0</p>

Rather than field_64aa869f48df7 we'd see text.
