Misspelling in hdb_catalog down migrations

### Version Information

Server Version: 2.6.0

### Environment

OSS

### What is the expected behaviour?

Certain migrations include this snippet:
```sql
WHEN ((rt.typtype) :: text = ('p' :: character(1)) :: text) THEN 'PSUEDO' :: text
```
`PSUEDO` is a misspelling of `PSEUDO`

I am unsure what impact, if any, this could have.
Please note these are all down migrations and are rarely used, so it is possible there _is_ and impact but it has never been brought up.

### Keywords

sql hasura schema migrations misspelling.

### Can you identify the location in the source code where the problem exists?

This happens in the following files: [13_to_12.sql](https://github.com/hasura/graphql-engine/blob/master/server/src-rsr/migrations/13_to_12.sql#L36), [22_to_23.sql](https://github.com/hasura/graphql-engine/blob/master/server/src-rsr/migrations/22_to_21.sql#L39), [23_to_22.sql](https://github.com/hasura/graphql-engine/blob/master/server/src-rsr/migrations/23_to_22.sql#L147)

### If the bug is confirmed, would you be willing to submit a PR?

Happy to open a PR, but only once it becomes clear what the potential impact is.

Start by reviewing the down-migration snippets in server/src-rsr/migrations/13_to_12.sql, 22_to_21.sql, and 23_to_22.sql at the locations identified in the issue. Check the impact of the misspelled PostgreSQL type label in these migrations before making a consistent correction; done means the affected migrations use PSEUDO and remain valid.
