Format the "Historical Era Composed" dates when there are multiples

[davidamichelson]

See testimonia 1, 43, 44, 220, 413, 414

For example https://caesarea-maritima.org/testimonia/220

Please put each of these date periods on a new line so they are all left justified and look tidy like this

Nabatean Kingdom, 167 BCE-106 CE
Early Roman Period, 36 BCE-132 CE
Herodian Period, 36 BCE-70 CE
Middle Nabatean Period, 24 BCE-50 CE

Save the code for this because we will be adding another kind of date to this box too and want to use the code for that too
