feat(Authoring): Translate with AI

[Aaron-Detre]

Changes

• Added an API endpoint to handle AWS Translate requests
• Changed Controller -> RestController since saveTranslations already had ResponseBody

Testing

• Test with feat(Authoring): Translate with AI WISE-Client#2272
• Add properties to application-dockerdev.properties (I think this is why the build failed?):

aws.accessKeyId=
aws.secretAccessKey=
aws.region=

• We need to handle case when aws settings are not specified in application.properties. Right now, the API throws an exception and won't start.
• Add the new aws settings to application_sample.properties and application-dockerdev-sample.properties, with explanation on what they're used for.

Rename endpoint to /api/author/project/translate/suggest

Suggested change

	@PostMapping("translationSuggestions")
	@PostMapping("suggest")

Instead of ObjectNode, create a class TranslatableText(?)
