Update Serval.Client to 1.12

[pmachapman]

This PR updates the Serval Client to version 1.12 (the version currently on QA).

This update to Serval.Client marks several the older corpus API endpoints as deprecated, so the code now clearly needs to demarcate whether a parallel corpus or a legacy corpus is being used to retrieve pre-translations.

This PR should only be merged when Serval 1.12 is deployed to production (likely later this week).

The current version of Serval.Client (1.10) will continue to work as per normal when Serval production is updated, so this PR is not a blocker in any way.

src/SIL.XForge.Scripture/Services/PreTranslationService.cs line 217 at r1 (raw file):

                textOrigin: PretranslationUsfmTextOrigin.OnlyPretranslated,
                template: PretranslationUsfmTemplate.Source,
                paragraphMarkerBehavior: config.ParagraphFormat switch

Could we move these two switch expressions to before the if statement, so they're precomputed, and don't have to be manually kept in sync with each other, and reviewed to make sure they're the same? (in other words, calculate the paragraphMarkerBehavior and quoteNormalizationBehavior once rather than twice).

Done. That looks better - thanks!
