Enable EMOJI compatibility for Configuration: Set default collation of field "value" in table "core_config_data" to utf8mb4_unicode_ci

[vbidou]

Description

Enable Emoji compatibility for values recorded inside the Table "core_config_data".
Current default collation for field "value" is utf8mb3_general_ci
This collation doesn't allow full EMOJI compatibility
This is possible to change the collation manually, but this change is lost during the next setup:upgrade due to the default DB schema of Magento.

Expected behavior

Allow full EMOJI compatibility by assigning default collation utf8mb4_unicode_ci to this field.

Benefits

Allow to use the full spectrum of EMOJI for the users.
