Posts getting duplicated in generated sitemap

[aamnakhan]

Hey! I see this was a problem earlier and it was fixed but I think it's crept back in? This is what my sitemap looks like. Same issue as #99 and #91

@aamnakhan Please ensure that you provide us with as much information as possible when reporting bugs. For example,

• what version of the plugin are you using? (bundle show jekyll-sitemap)
• what version of Jekyll are you using? (bundle exec jekyll --version),
• list of any other plugins your site is using.. etc

@aamnakhan The issue is with the incorrect usage of include configuration. You should not include _posts in the array. Posts are internally seen as a Collection and they get processed at all times as long as the filename follows the YYYY-MM-DD-TITLE format.
