Doc hotfix: Correct date formats

Description

• Category: documentation
• JIRA issue: none

Previously our docs said all datasets had dates in YYYY-MM-DD. In fact, this is not the case.

You can see that this matches the code here:

pseudopeople/src/pseudopeople/interface.py

Lines 120 to 127 in d1bf3be

	if COLUMNS.ssa_event_date.name in data.columns and dataset == DATASETS.ssa:
	# event_date -> YYYYMMDD
	data[COLUMNS.ssa_event_date.name] = data[COLUMNS.ssa_event_date.name].dt.strftime(
	"%Y%m%d"
	)
	if COLUMNS.dob.name in data.columns:
	# date_of_birth -> MM/DD/YYYY
	data[COLUMNS.dob.name] = data[COLUMNS.dob.name].dt.strftime("%m/%d/%Y")

Note that this code is also wrong, in that it does not match the concept model.
I will make another PR against develop to get everything (code and docs) in alignment with the concept model.

Testing

Built docs locally.

Idea: allow users to choose any date format in the config, and use these as the defaults
