Predefined layout identifies don't localize dates and times

I tried to follow the docs here:

With this config.toml

baseURL = "http://example.org/"
defaultContentLang = "de"
languageCode = "de_DE"
title = "My New Hugo Site"

and this in index.html I don't get german localization.

<p>{{ .Date | time.Format ":date_full" }}</p>
<p>{{ .Date | time.Format ":date_long" }}</p>
<p>{{ .Date | time.Format ":date_medium" }}</p>
<p>{{ .Date | time.Format ":date_short" }}</p>
<p>{{ .Date | time.Format ":time_full" }}</p>
<p>{{ .Date | time.Format ":time_long" }}</p>
<p>{{ .Date | time.Format ":time_medium" }}</p>
<p>{{ .Date | time.Format ":time_short" }}</p>

Which version are you using?

With v0.89.0 and later, with date = 2022-03-04T08:01:53-08:00 in front matter, in my locale your code+configuration produces:
