.Format Function converts '+' to &#43; even when contained inside a <time></time> tag

[Bas-Man]

What version of Hugo are you using (hugo version)?

Hugo Static Site Generator v0.74.1/extended darwin/amd64 BuildDate: unknown

Does this issue reproduce with the latest release?

Yes. This is the latest version and I only initially noticed it after updating as I am trying to workout a different issue.

I suspect this is a bug as it would seem that:

+

would not conform to the specification for the tag as noted at https://www.w3schools.com/tags/att_time_datetime.asp

Seems there might be a need for the .Format function to be able to preserve the '+' character in some cases.

Example of code from a the Ananke theme I am currently using

      {{/* Hugo uses Go's date formatting is set by example. Here are two formats */}}
      <time class="f6 mv4 dib tracked" datetime="{{ .Date.Format "2006-01-02T15:04:05Z07:00" }}">
        {{- .Date.Format "January 2, 2006" -}}
      </time>

Produces

     <time class="f6 mv4 dib tracked" datetime="2020-07-16T00:00:00&#43;09:00">July 16, 2020</time>

This issue may actually trace back to the actual .Date and .Lastmod function.
I have found that the same issue occurs even without the .Format function.
