handle repository.size column being NULL in migration v263 (#28336)

Browse Source 
This resolves a problem I encountered while updating gitea from 1.20.4
to 1.21. For some reason (correct or otherwise) there are some values in
`repository.size` that are NULL in my gitea database which cause this
migration to fail due to the NOT NULL constraints.

Log snippet (excuse the escape characters)
```
ESC[36mgitea                |ESC[0m 2023-12-04T03:52:28.573122395Z 2023/12/04 03:52:28 ...ations/migrations.go:641:Migrate() [I] Migration[263]: Add git_size and lfs_size columns to repository table
ESC[36mgitea                |ESC[0m 2023-12-04T03:52:28.608705544Z 2023/12/04 03:52:28 routers/common/db.go:36:InitDBEngine() [E] ORM engine initialization attempt #3/10 failed. Error: migrate: migration[263]: Add git_size and lfs_size columns to repository table failed: NOT NULL constraint failed: repository.git_size
```

I assume this should be reasonably safe since `repository.git_size` has
a default value of 0 but I don't know if that value being 0 in the odd
situation where `repository.size == NULL` has any problematic
consequences.
