feat(dtables): add dolt_status_ignored system table adapter

Add adapter and test expectations for the new dolt_status_ignored
system table from PR dolthub/dolt#10227. This table provides the same
information as dolt_status plus an additional ignored column
indicating whether unstaged new tables match a pattern in dolt_ignore.

Changes:
- Add DoltgresDoltStatusIgnoredTableAdapter in status_ignored.go
- Register DoltgresDoltStatusIgnoredTableAdapter in init.go
- Update pgcatalog_test.go with new dolt_status_ignore table to expected
tables
- Add new dolt_status_ignore table to sequences_test.go expected tables
