Fixes incorrect where condition when deleting swatch option, it delet…

[hostep]

…ed all options instead of a specific one.

Description (*)

This fixes an incorrect where condition in the SQL query which should delete a specific swatch option.
It changes the SQL query from (which deletes all options):

DELETE FROM `eav_attribute_option_swatch` WHERE (option_id)

to (9 is an example here):

DELETE FROM `eav_attribute_option_swatch` WHERE (option_id = 9)

Fixed Issues (if relevant)

1. Changing attribute from swatch to dropdown deletes swatch options for all attributes #20396: Changing attribute from swatch to dropdown deletes swatch options for all attributes

Manual testing scenarios (*)

See description in #20396
You don't need products, just create 2 swatch attributes, and change one of them to dropdown to reproduce the problem.
