[Bug]: Improper post date format in some cases

[Habetdin]

What happened?

Raw (unformatted) .Date is used here:

hugo-PaperMod/layouts/_partials/post_meta.html

Line 4 in 154d006

{{- $scratch.Add "meta" (slice (printf "<span title='%s'>%s</span>" (.Date) (.Date | time.Format (default ":date_long" site.Params.DateFormat)))) }}

... which leads to duplicate timezone information. Reasons are described here: gohugoio/hugo#5907, gohugoio/hugo#9096

This issue could be fixed by using explicit formatting like this:

diff --git a/layouts/_partials/post_meta.html b/layouts/_partials/post_meta.html
index c7c2635..decaef3 100644
--- a/layouts/_partials/post_meta.html
+++ b/layouts/_partials/post_meta.html
@@ -1,7 +1,7 @@
 {{- $scratch := newScratch }}

 {{- if not .Date.IsZero -}}
-    {{- $scratch.Add "meta" (slice (printf "<span title='%s'>%s</span>" (.Date) (.Date | time.Format (default ":date_long" site.Params.DateFormat)))) }}
+    {{- $scratch.Add "meta" (slice (printf "<span title='%s'>%s</span>" (.Date | time.Format "2006-01-02T15:04:05-07:00") (.Date | time.Format (default ":date_long" site.Params.DateFormat)))) }}
 {{- end }}

 {{- if (.Param "ShowReadingTime") -}}

Another file worth checking:

hugo-PaperMod/layouts/_partials/templates/schema_json.html

Lines 93 to 94 in 154d006

	"datePublished": {{ .PublishDate }},
	"dateModified": {{ .Lastmod }},

Steps to reproduce

1. Create post with date in timezone that doesn't match system timezone
2. Publish it
3. Check the date format in the post meta
