hey @NekoSakuraLucia, thanks for this PR.

i'm not sure about this change since it's not mentioned in the official facebook reference: https://developers.facebook.com/docs/sharing/webmasters#markup

while it is part of the open graph protocol, each platform decides what to implement, so i'm unsure if this tag is actually supported.

The use of the og:site_name tag is part of the Open Graph Protocol, and Facebook supports this tag to display the name of the website from which the content originates when shared on the Facebook platform or other services that support Open Graph.

the thing is, as I mentioned, not all open graph tags are supported by Facebook some og:tags are just skipped. do you have any way to confirm if this tag is actually supported? as you know, i prefer not to add anything unnecessary. i’ve ensured this package includes only the minimal set of supported tags.

[NekoSakuraLucia]

@mhdcodes Actually, the og:site_name tag is not explicitly mentioned in Facebook's Open Graph documentation. However, based on practical usage, this tag is generally supported and is used to display the website name when sharing a link on Facebook. You can try debugging it yourself using a tool to test meta tags. If I’m not mistaken, there’s a website for testing this.

[mhdcodes]

yeah there are websites to try this, I will do the testing and let you know. thanks for the great work @NekoSakuraLucia
