[BUG] Author tag is not show correctly in RSS file

[victor-pogor]

Describe the bug

As @jadmadi reported on PR #113, the <author/> tag in the RSS XML file is not showing correctly. I checked the theme via W3C RSS Validator and I found two problems:

1. Invalid email address: Author
2. Self reference doesn't match document location: https://example.com/index.xml

I found that email should have a specific format. The problem is that not all authors would like to reveal their email. For this purpose, there is another tag (dc:creator). The value of the dc:creator element is less restrictive than the author element, which must contain an e-mail address.

Expected behavior

• If the email is indicated in config.toml, show the author tag.
• If the name is indicated in config.toml, show the dc:creator tag.
• Show correct document location
