feat: add Spotify Search plugin

[wesssel]

Hi!

I wrote two guest articles on Storyblok related to this topic:

• https://www.storyblok.com/tp/how-to-fetch-spotify-data-with-a-field-type-plugin
• https://www.storyblok.com/mp/spotify-field-type

Would be great if we can add this plugin as an example

Hello @wesssel, thank you for creating this awesome field plugin. Looks great 🚀

A suggestion for the future (no need to implement it) would be to look into error handling. For example, how should the field plugin behave when the Spotify API returns an error? I think it could be a nice extension also to the article you have written. 🔥

We are currently checking how we want to proceed with this repo, so until we decide that, we would keep this PR open and in case of any changes, instruct you of course on what to do.

PS: If you have any feedback regarding the developer experience when implementing a field plugin, we will be more than glad, to collect your thoughts on it, so do not hesitate to reach out 🙏

@BibiSebi thanks for the feedback! I will keep the error handling in mind for future plugins.
