invalid date can be used if only the 10-digit date string is supplied

[ElectricNroff]

Following up on the #817 issue, invalid dates such as February 31 are rejected only if the user chooses to provide a time:

/cve-id?time_reserved.gt=2023-02-31T00:00:00Z
==>
Bad date, or invalid timestamp format: valid format is yyyy-MM-ddTHH:mm:ss or yyyy-MM-ddTHH:mm:ss.ZZZZ

/cve-id?time_reserved.gt=2023-02-31
==>
{"cve_ids":[]}

Lines 128 to 137 in 11e75ef

	const valid = validateDate(dateStr.toString().substring(0, 10), responseType = 'boolean')
	if (valid) {
	result = new Date(dateStr)
	}
	} else {
	value = val.match(/^\d{4}-\d{2}-\d{2}$/)
	if (value) {
	result = new Date(`${value[0]}T00:00:00.000+00:00`)
	}
	}

puts validateDate outside of the code block where the time is omitted.
