.NET 7 + Spring Cleaning (#1677)
* Updated to net7.0

* Updated GA to .net 7

* Updated System.IO.Abstractions to use New factory.

* Converted Regex into SourceGenerator in Parser.

* Updated more regex to source generators.

* Enabled Nullability and more regex changes throughout codebase.

* Parser is 100% GeneratedRegexified

* Lots of nullability code

* Enabled nullability for all repositories.

* Fixed another unit test

* Refactored some code around and took care of some todos.

* Updating code for nullability and cleaning up methods that aren't used anymore. Refctored all uses of Parser.Normalize() to use new extension

* More nullability exercises. 500 warnings to go.

* Fixed a bug where custom file uploads for entities wouldn't save in webP.

* Nullability is done for all DTOs

* Fixed all unit tests and nullability for the project. Only OPDS is left which will be done with an upcoming OPDS enhancement.

* Use localization in book service after validating

* Code smells

* Switched to preview build of swashbuckle for .net7 support

* Fixed up merge issues

* Disable emulate comic book when on single page reader

* Fixed a regression where double page renderer wouldn't layout the images correctly

* Updated to swashbuckle which support .net 7

* Fixed a bad GA action

* Some code cleanup

* More code smells

* Took care of most of nullable issues

* Fixed a broken test due to having more than one test run in parallel

* I'm really not sure why the unit tests are failing or are so extremely slow on .net 7

* Updated all dependencies

* Fixed up build and removed hardcoded framework from build scripts. (this merge removes Regex Source generators). Unit tests are completely busted.

* Unit tests and code cleanup. Needs shakeout now.

* Adjusted Series model since a few fields are not-nullable. Removed dead imports on the project.

* Refactored to use Builder pattern for all unit tests.

* Switched nullability down to warnings. It wasn't possible to switch due to constraint issues in DB Migration.
