Release/gp7 2.2.2 (#361)

Change the CI pipeline to release diskquota for GP7.

TODO:
- enable regress test on CI.
- enable activatestandby test for GP7 on CI.
- fix regress test for GP7. The view in GP7 will be treated as a relation by diskquota. After `CREATE EXTENSION`, the test case should execute `SELECT diskquota.init_table_size_table()` to make the diskquota.state ready on GP7.
