Fix dynamic metadata object in docs

[antonioberben]

Simple fix in the documentation.

Dynamic Metadata should be a key-value json object like: {"my-new-metadata": "my-new-value"}
In the docs it is: {"foo", "bar"}

Thanks! The docs say it's an object, so this change seems correct to me, but there's also a later section after "With the input value above, the value of all the variables in the package are:" where this is displayed as a set/array, so you'd need to change it there too for this to be consistent.

@anderseknert , where can I find that? the line is this one, but I can't find where the source is

Hi @anderseknert , can you point me to the file I have to change? I cannot find it. Thanks!

@antonioberben sorry for the delay! I had somehow missed your first ping. On closer inspection I see that the code block I was referring to is auto-generated from the input and policy, and when I check the netlify preview it looks like it should. I'm sorry about that! All good then 👍
