feat: support i18nMonth for date in list item

[hucste]

if i18n exists, the month into this list item is not correctly displayed. Actually, only in english.
With this fixe, month is displayed segun language code.

So as the comment in config.toml,

hugo-theme-meme/config-examples/en/config.toml

Lines 449 to 450 in a7c47aa

	# Translate the month? (valid for title)
	i18nMonth = false

I don't think this is a bug. Though, it could be an enhancement.

Also, in your code, if i18nMonth is enabled, then the listDateFormat will not be respected -- it's hard-coded to "January 2" format. But there are many different date formats in different countries, see:

• https://en.wikipedia.org/wiki/Date_format_by_country
• https://gohugo.io/functions/format/

In other words, the character is i18ned but the format is not, or is destroyed.

Ok, I understand the problem. For the moment, I don't known how fix it.
but you have to admit that having the dates, once in FR (or other lang), once in EN, so sucks. :(
(I thought I'd come up with a solution and move things along...)
