test: ? literal in regexp_like

[ericsun2]

Explain your user case and expected results

When ? literal is part of the SQL statement for regexp pattern (not as a placeholder), gorm will still treat such literal as a placeholder and hence throw an error.

For example:

select name, age, birthday, active from users where name ~ '(zh)?.*' and name like ?

This is a bug in https://github.com/go-gorm/gorm/blob/master/clause/expression.go - https://github.com/go-gorm/gorm/issues/6889

you can use '%in%' instead of Regex
