chore: upgrade to https://code.forgejo.org/xorm/xorm v1.4.0 (#12639)

Upgrade Forgejo to our forked [xorm v1.4.0](https://code.forgejo.org/xorm/xorm/compare/v1.3.9-forgejo.12...v1.4.0), which is now named `code.forgejo.org/xorm/xorm` to reflect the current expectation that it is a permanent fork.  A small number of API changes were made recently in https://code.forgejo.org/xorm/xorm/issues/120 which are accounted for in this PR, in addition to the module rename.
