Apply Arabic and inline type styles in transcriptions

[blms]

Testing notes (QA)

On the public QA site:

• For a document with an Arabic transcription, confirm the transcription has the new Arabic type styles (Amiri font)
• Edit a transcription to add bits of Arabic script inline in the middle of a Hebrew transcription, and vice versa. Mark them up with the appropriate language using the "language" markup tool in the text editor (the globe icon).
• Save, and confirm you see the fonts applied correctly (Amiri for Arabic inside Hebrew, and Frank Ruhl for Hebrew inside Arabic).
• Confirm there is no visible decimal point or stray pixels next to line numbers.

dev notes

• Apply type styles based on primary language (already done for Hebrew but not Arabic)
• Apply type styles for inline language tags
• Nudge the dot cover

@blms @rlskoeser I do see these decimals on the transcription display in both public and admin

Closing this based on the primary functionality passing tests; should not have been kept open for the small display issue. If that remains an issue we can open a new ticket to investigate.
