Special treatment for Scripture references

[mvahowe]

These seem to confuse DeepL and, also, need to be not altered if we ever want to construct clickable links. My approach to this class of problem so far has been

• identify the relevant text using regexes
• replace them with uid placeholders, store the original values
• do the translation
• swap the original values back in

In addition, while we're doing this, we should convert the Tyndale reference format to the standard USFM one, including canonical book abbreviations.
