Incorrect resolution when there are multiple Open Graph tags

[SeriousBug]

The Open Graph protocol states that if there are multiple tags, the first one should be preferred in cases of conflicts. See here: https://ogp.me/#array

But article-extractor prefers the last tag. The code gets all the meta tags in the page, and iterates over them. If there are multiple tags, the last one will override earlier ones: https://github.com/extractus/article-extractor/blob/main/src/utils/extractMetaData.js#L98-L127

@SeriousBug yes, I consider that if we get all the values and push them into an array, the output will become more complex and not easy to keep consistent.

[SeriousBug]

Not grabbing all the tags in an array is absolutely a valid design decision. But I think article-extractor should still prefer to scrape the first image rather than the last one.

@SeriousBug thank you for your suggestion. I will consider to apply this to the next release.
