Bug 30899: [MASTER 22.12] Correct dbrev 211200041

Replace DROP CONSTRAINT by DROP FOREIGN KEY.

Note: It seems that we do not need a new dbrev for master. A developer
could follow test plan below to correct if really needed.

Test plan:

NOTE: When you check show create table, verify that you see an index for
category_code and a foreign key called borrower_attribute_types_ibfk_1.

[1] cp installer/data/mysql/db_revs/211200041.pl
installer/data/mysql/atomicupdate/
[2] run updatedatabase; check show create table
[3] alter table borrower_attribute_types drop foreign key
borrower_attribute_types_ibfk_1; alter table borrower_attribute_types drop
index category_code; RUN updatedatabase again; check show create table
[4] alter table borrower_attribute_types drop foreign key
borrower_attribute_types_ibfk_1; ALTER TABLE borrower_attribute_types ADD
CONSTRAINT category_code_fk FOREIGN KEY (category_code) REFERENCES
categories(categorycode); RUN updatedatabase again; check show create table
[5] rm installer/data/atomicupdate/211200041.pl
