fix: allow set_version to fail, but don't commit in that case

The only table that has been added since DB version 6 (the earliest supported version), is the versions table in DB version 101.
This commit removes the "create all tables" statement, and instead creates the versions table in the 101 migration.
See 12e074b71d.

 Two packages are provided: `tagstudio` and `tagstudio-jxl`. The distinction was made because `tagstudio-jxl` has an extra compilation step for [JPEG-XL](https://jpeg.org/jpegxl) image support. To give either of them a test run, you can execute `nix run github:TagStudioDev/TagStudio#tagstudio`. If you are in a cloned repository and wish to run a package with the context of the repository, you can simply use `nix run` with no arguments.
