Cleaned dependencies and improved missing translations

[ErikApption]

The current version of this localizer breaks our MAUI builds because of legacy packages

• Added .net 6 specific build
• Removed legacy packages for .net 5 and .net 6

I added several other improvements in this path:

• support for AdditionalResourcePaths - in a current app I'm working on, we need custom paths to load localization resources
• got wasm working with embedded resources - which seems to be the only option unless someones figures out how to propagate the async context (and wasm doesn't let you cheat with async.Result)
• removed the newtonsoft.json in the wasm build, this should also satisfy dependabot

@AlexTeixeira can you have a look pleeeaassseee

Added another feature for ignoring files with Json errors. This should not be enabled in dev (default is to disable this feature - aka the localizer will throw an exception) otherwise translations will fail without clear reasons but in prod, we don't want the site to crash because of a json file.
