Better date displays - processing level display

[danyx23]

This PR improves the rendering of some dates and time ranges, updates the processing level (minor/major) text and fixes some minor wording issues.

This is related to #2755 and fixes these points:

• Instead of mentioning Twitter (in "How to cite this data"), we should say "social media".
• We should not say "OWID" anywhere (as it happens in "How to cite this data").
• We should show the date of next expected update. This should be based on dataset.update_period_days and the current date (if it's passed, increase it by a month).
• Change the wording of "processed" or "adapated" by under the chart to "with minor/major processing by Our World In Data"
• If the time range for an indicator includes negative years (like our long run population data does), then show 10000 BC to 2020 AD instead of -10000-2020
• Last updated date should render as a formatted date instead of a raw date string

Looks good! I only have a couple of very minor comments. Formatting dates nicely makes a surprisingly big difference :)
